MENOW TITLE: Intrinsic Optic Absorption in Amorphous and Crystalline Germanium PERIODICAL: JPixika tver&ogo tela, 1960, Vol. 2, No. 1, pp. 45 - 47 TEXT: For cosparisonp the authors studied the amorphous and the crys- talline germanium within the rang* of strong absorption. The absorption coefficients were determined on the strength of measurement results of the passage of light through and its reflection from thin foils on quartz base. A certain shrinkage was always found to occur with the crystallization of amorphous foils. This reduction in thickness by 5-9% in indicative of a transition to a denser packing of the atoms. The optical proportion of the foils were measured in the airg as soon as possible after their removal from vacuuma The authors detected some ualitative characteristics of the optical properties of amorphous Zoolid lines) and crystalline (broken lines) germanium (Fig. 1). The reduced absorption coefficients k(X) for calculated values of the Card 1/2 Intrinsic Optic Absorption in Amorphous and S/181160/002/01/09/035 CrytbMine Germanium B008/Boll spectral characteristics are shown in Fig. 2. It may be stated that amorphous and crystalline germanium resemble each other as to their optical properties. They have the same range of intrinsic absorptiong whose general course and Intensity do not exhibit any great differences, although there are son* distinctly marked qualitative differences. These are caused by differences in the long-rang* order. The authors thank L. Apkerp R. R. Philippq and E. A. Taft for communicating their in- vestigation results in advance of publication.

TITLE: Current-voltage Characteristics of the Photoelectron Emission of Germanium PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 2, pp. 306-313 TEM The authors report on investigations of the current-voltage characteristics of photoelectron emission of germanium layers with a low work function. P. I. Lukirskiy (Ref. 1) has already shown that these characteristics can be obtained in the field of a spherical condenser when the diameter of the emitter is small compared with the diameter-of the collector. For the investigations germanium was vaporized on a metal disk in vacuum. With strongly reduced work function of the electrons from the germanium surface, the contact potential difference between the front, the emitting, and the back layers of the disk forms a barrier field for the photoelectrons, as is shown by model experiments in the electrolytical tank of Fig. 1. For investigating the current-voltage characteristics of germanium of three-electrode device was used whose Card 1/3 817717 Current-voltage Characteristics of the S/181160/002/02/21/033 Photoelectron Emission of Germanium Boo6/Bc)67 schematical drawing is shown in Fig. 2. Its construction is described in detail. The results which are shown in diagrams are discussed after a detailed description of the experiments. Fig, 3 shows the oharacteria- ties which were recorded at an irradiation wavelength of 240, 254, 280, 313, 365, 435, and 546 mu. A quartz monochromator with a "K-4 (PRK-4) lamp served as light source. The energy distribution of the emitted electrons is discussed in the following.

The germanium films were sputtered onto tungsten backings, cold as well as at T = 4500C. Electron diffraction studies showed that the films sputtered at room temperature were amorphous, and crystalline at increased temperature. An investigation of the contact potential differences between the amorphous and crystalline films produced under otherwise equal conditions showed that the thermoelectronic work function of the latter was some ton electronvolts smaller than that of the former. Fig. I shows the change of the work function 64(t) with time of simultaneously sputtered BaO for crystalline (Curve 1) and amorphous (Curve 2) films. The values of the primary photoelectronic work function of crystalline germanium films are Card 1/3 81,778 Photoelectronic Emission of Germanium and Sili- B/181/6()/002/02/22/033 con in the Amorphous and Crystalline States BOo6/Bo67 lower than those of amorphous ones. Experiments were also made with monocrystalline p- and n-type germanium samples. The preparation of these samples is described; the pure surfaces of the single-crystal samples were obtained in such an evacuated tube as shown in Fig. 2. Fig- 3 shows the spectral characteristics of the photoelectronic emis- sion of three crystalline germanium samples with reduced work function. Curve 1 refers to high-resistance single-crystal germanium, Jurve 2 to n-type Go single crystals with 3 ohm.cm, and-Curve 3 to a crystalline film, Fig. 4 gives a comparison of the spectral characteristics of amorphous and crystalline germanium. Similar investigations were also made with silicon. The amorphous films were obtained by sputtering onto * backing at room temperature, the crystalline ones were obtained from * p-type single crystal in high vacuum. The spectral characteristics of these samples are also shown in Fig- 4- For comparison, this diagram also shows the characteristics of the spectral sensitivity of W - BsO photocathodes and two Cs 3Sb samples. In contrast to amorphous germanium, crystalline germanium shows a weak minimum in the short-wave region, which corresponds to the maximum of the spectral characteristic of the optical Card 2/3 0~ 81718 Photoelectronic Emission of Germanium and Sili- 5/181/60/002/02/22/033 con in the Amorphous and Crystalline States B006/BO67 reflection of crystalline germenium. Amorphous samples do not even have this maximum. Since optical absorption In silicon is weaker than in germaniumv the photoelectronic sensitivity of silicon is also lower. Such a parallel cannot be observed in a comparison of germanium and Cs-Sb. In conclusiont the authors,thank Professor D. N. Nasledov for the pr2paration of the Si single crystals, Ye. G.

TITLE: Optical Properties and Photoelectron Emission of Amorphous and Crystalline Germanium Films PERIODICAL; Fizika tverdogo tela, 1960, Vol. 2, No. 12, pp. 3020-3025 TEXT: The optical properties of germanium films within the range of intrinsic absorption have been studied many times. The types of filmsp however, were not named. Following a previous paper (Ref. 2) in which the spectral characteristics of transmissivity, reflection, and absorp- tion, of amorphous and crystalline germanium films were studied, the authors have now analyzed the results obtained and determined the influence of the type of film upon these characteristics. The experiments were repeated with an improved method, and more exact results were obtained since various corrections (eg., for the spectral dependence of the refractive index) were taken into account. The device used for the purpose is illustrated in Fig. 1 and described in detail. The authors studied the spectral characteristics of the reflection and transmission Card 1/4 879o6 Optical Properties and Photoelectron Emission S/181/60/002/012/006/018 of Amorphous and Crystalline Germanium Films B006/BO63 coefficients, and determined the influence of the atmosphere (air, vacuum).

The dotted lines obtained by Philipp and Taft (Ref. 5) show k(A) and n(A) for single crystals of germanium, without taking account of the oxide film on the surface. The effect of optical peculiarities of the films Upon the characteristics of photoelectron emission was studied with the same device. There are 6 figures and 6 references: 4 Soviet and 2 US.

It was established that the optimum value of the yield effect in respect to the photo-electronic emission is achieved for a-metal surface at values t within th? limits 4-20 and for the surface of Mg,,Sn at tt7o. it can also be seen that in the case of a photoelectronic yield erfect of only about 2 ev, the values of the quantum yield in M'923n remairi small, reaching only the tenth part of a percent even at the highest values of h9 = 5 ev.

TITLE: Optical properties and photoolectron emission of Mg,~Sb2 I PERIODICAL: Fizika tverdogo tela, v. 3, no. 6, 1961, 1778 - 1785 TEXT- Mg3 Sb 2' the intermetallic compound of type 11_~L -Vbstudied the most thoroughly heretofore, has been examined by the authors for its photoelec- tric and optical properties. The Mg3Sb 2 films used for the investigation were prepared in different ways from pure magnesium and pure antimony% the initial substances had been supplied from the Institut obshchey i neorganicheskoy khimii AN USSR (Institute of General and Inorganic Chemistry AS UkrSSR) by V. P. Zosimovich. The photoelectric characteri s tics of thefiIns prepared in three different ways were the same. A method described pre- viously (FTT, II, p. 45 and P. 3020, 1960) was used to determine the optical constants: the measurement of the reflection and transmission coefficents of light under exposure from front and rear. The monochromator Card 1/4 24919 Optical properties and photoelectron... SIIB1161100-100610161031 B102/B201 of an C~-4(SF-4) spectrophotometer was employed for measuremenzs in the 254 - 578 m~L spectral range, while a YtI-2(UM-2) monochromator was used for the 450 - 1100 m/k range. An OCK-12 (ISK-12) spectrometer was used wi~_.I ;WOOO m/k. Since absorption is dependent uponX ', variously thick films were used for different spectral ranges. Since, however. a considerable light scattering was already observable for d~ I , the longwave limit for the experiments was set at hV - 1.55 ev. For wavelengths outside the region of self-absorption, only the refractive index was determined, namely, by an interference method. Films up to 3,U-could be used for this purpose. Beyond the self-absorption region the refractive index was 1i - 4.7, and the dielec- tric constant at high frequencies was k = M1. As may be seen from dia- grams (1-R) .,f(hv), light with hV> 3.3 ev is practically absorbed fully in jayers of 50 m~&. The light source in the measurements of photoelectron emission (with SF-4 and Kn-28(ISP-28)) was provided by a mercury-quartz lamp of the type nPK-4(PRK-4); the light energy at the input of the mono- chromator was determined by means of standard photocells. The photocurrents were measured by a d-c amplifier.

TITLE- A new type of alternating photoconductivity in cadmium selenide crystals PERIODICAL: Fizika tverdogo tela, V. 4, no. 1, 1962, 296 - 297 TEXT: Alternating photoconductivity was observed on CdS crystals with 6 resistivity of 10 ohm-cm, which were provided with indium contacts and placed in a high vacuum.- This photoconductivity was essentially different from that observed by Harnik and Weisz. The spectral characteristic, illustrated by curve W/W = f(;L) clearly shows the change in sign of photoconductivity, which occurs at 520 - 530 MIA. Harnik and Weisz observed such a change at ;L> 650 mp AI/W denotes the illumination-induced increase of current related to equal values of luminous energy. The course of the volt-ampere characteristics also reveals this alternation in photoconducti-d-, ty, which is always positive at weak fields, becoming negative at fields of the order of 102v/cm. Harnik and Weisz found negative phot-oconducti-,rity at weak and medium fields, with the change to positive at E> 104 v/cm. The Card 1/2 A new type of alternating ... 33371 S/181/62/004/001/049/052 B112/B138 authors succeeded in producing a crystal in which the change in sign could also be observed in dependence on the illuminated part of the crystal.- One part displayed this alternating photoconductivity, and the otheronly positive iphotoconductivity, independent of A or voltage applied. The lux- ampere characteristic of the latter is norm alv that of the negative photo- conductivity shows a rapid incrpase-up'to -15-lo-7a, then it remains constant Its mechanism may be explained on the assumption of photoexcitation of minority carriers from local levels, which recombine with majority carriers. Applied to the change in photooonductivity, however, this model is compli- cated by the voltamperage charaDteristics, which indicate that field not only determines its level, but also the sign.

Emission of non-equilibrium electrons from cadmium sulfide PERIODICAL: Fizika tverdogo tela, v. 4, no. 11, 1962, 3003 - 3009 TEXTs The characteristics of non-equilibrium electron emission ftmCdS crystiib i.; were investigated and the effect 9f illumination was measured. In a previous work (FTT, 3, 2186, 1961) it had been shown that the electron emission from CdS is affected by an electric field far stronger than that: due to the potential difference applied. An bhmic probe was used to measure this field along the crystals before and after,the treatment known as "forming". In the previous work the treatment was given in vacuo' whereas now- it was carried out in air. This was found to have a substantia effect on the potential distribution within the crystal (Fig. 1). The strong field was observed also in the electrooptical effect. The forming leads to the formation of two zones within the crystal which are separated by a thin layer (0.02-0.06 mm) exhibiting a high potential drop. This separating layer, can be made visible in transmitted light (jL520q_VA)1. At Card 1/4 S/161/62/004/011/001/049 Emission of non-equilibriuip, n. B102/BIO4 the point where the potential drops sharply, the electron emission current has a peak. Further, the forming either increases or decreases resistivi- ty; some crystals showed aikind of rectifying effect. In most cases, the emission increased considerably on being illuminated, whereas in some cases emission occurred already at potentials much lower than those re_ V quired for observing dark emission. Illumination with hw< 5 ev produces no electron emission if no potential is applied to the crystal or if no current is flowing through it. The conductivity of some crystals was found to be completely Independent of illumination. In order to clarify these effects, the spectral characteristics of photoconductivity and light emission were measured. The results differed between various crystals. For the crystal whose potential distribution is shown in Fig. 3, the energy of the electrons emitted was calculated from the emission current density to be -_ 1.4 ev. Thelfield strength within this crystal appears to have the order of 2-3-10v/cm, which is high enough for the electrons to collect sufficient energy:for emerging into the vacuum. On illumina- tion, photoconducting crystals increase the conduction electron concentra- tion and moreover intensify..the field in the emitting regione, thus causing or intensifying the,dark emission.

One method is based on the use of radiosonde date and the second an the-general patterns of distribution of humidity in the free atmosphere. The methods were developed on -tho basis of data from a large number of cases. but the effectiveness of the methods has not been checked under various synoptic conditions. .

The error to this method does not exceed 8-10L. The described method is unsuitable when the radiosonde station is ever 150-200 ke distant or when the radiosonde data is over 9 bours old. In amb cases it is possible to use three fonw1as derived by the author which give the same results with an error of 15-209. Thus, on the basis qf the results the first method to Imore successful.

The fluxes used in the automatic and semiautomatic are welding of Ti and- its alloys are more or. less hygroscopic, since they contain chlorides of alkali and alkali-earth metals. .. This harbors the danger of the contamination of the Ti and Ti-alloy weld metal with oxygen a-ad hydrogen. Hence, the author has experimentally. developed a nonhygroscopic welding flux on investigating 10 different compounds. Findings: the minimum (virtually nil) hygroscopicity is displayed by BAF -B'C'2 and 2 SrF2*SrCl compounds. Since the salts of Ba absorb X-rays and thus complicate 420graphe inspection inclusions in weld metal, the nonhygroscopic flux was ~ Lra of slag developed on the-515.11 or the compound SrF2'SrC'2. The compound was malted on usiog UDC: 621.791.04:669.295 rnrd 1/2 L 00673-67 ACC NRs AP6015251 44.5 wt.% SrF2 and 55.5 wt.% SrCl2 and the flux base, an using wt.% NaF. After this-both the compound and the flux 99 wt'% CaF2 and: anulated to the base-were gr required size by cruShiAg,and sieve-screening and automatically mixed in mutual pro- portions of 7 and 93% by weight, respectively, thus assuring a 4 wt.% content of composition 'of SrF2*SrC'2. The flux ob- SrC12 in Accordance with the stoichiometric tained by-this method pr6duce's.-Satisfact*ory-volde-lh the prenuce Of welding currents of up to 600-700 a. The weld surface is lustrous, silvery, which demonstrates that the slag provides adequate protection for not only the weld pool but alsothe solidifying weld. This is of great significance to multi-layer welding, since it dispenses with the need to clean the surface by mechanical means every time before the next.layer is deposited. This newly developed welding flux has been named A-H-Tll. The insignificant hygroscopicity it displays is chiefly due to the absorp- tion of moisture at grain boundaries. When exposed to air, this flux virtually does not absorb any moisture. Tests of mechanical properties of the 10-M thick joints of N VTl technical titanium welded with the aid of this flux produced satisfactory re-. Fiults. Orig. art. ham 2,figures and 1 table.

When the foil 4 L-134-04-66 f-b ACC NR: AP6015319 was absent and the grid was at ground potential the current to the collector was small and indepondent of thexesidual gas pressure. When a positive, ,A-0tential was applied to the grid the collector current increased with Increasing reiUual gas pressure. When the grid was 200 V positive the collector current was 10 WON greater at a re- sidual gas pressure of 2 x 10-2 mm. 11C than at high vacuum or witk,ihe grid grounded. Similar behavior was observed when the 10 micron aluminum foil 4 was in place. 7be observed effects are ascribed to compensation of the-space charge of the beam by positive ions of the residual gas. It is suggested that the effect of the pasitively-:. charged grid 2 is to prevent escape of positive Ions from the Interior of the metalll tube 3. Orig. art. has: 2 figures.
