TITLEi Electron properties of thin films of germanium PERIODICALs Radiotekhnika i alaktronika, Vol.5, No.10, 1960, pp~ 1669-1671 TEXTt This paper was read at the 9t.h All-Union Conference on Cathode Electronics in Moscow, October, 1959. The aim of the present work was to investigate the electrical conductivity of thin germanium films of various thicknesses and changes In the ele.ctrical conductivity due to heat treatmentj oxidation, etc., In distinction to previously published work, the present authors state that they have cagried out their measure- ments in "ultra-high vacuum" (p,< 1. 10- mm Hg). In ordinary -acua one always obtains pz-tyAe~,germanium films (owing to contamination by residual gas), while in ultra-high vacua n-type germanium films can be obtained, In the present experimonts, n-type germanium films with' e r 26.,2 ohm cm were obtained,, A special glass envelope was made whith was used to measure the resistance of 12-13 films obtained in a single evaporation run.

E032/E114 were employed and the thickness of the films war, determined by calculation from the geometry and weight of the _,4pecimens. Fig.1 shows the logarithm of the resistivity as a function of thickness (microns).

Fig.2 shows dependence of I/od on log d (I - fresh deposit of Ge; 2 - oxygen atmosphere at 5 x"10-7 mm Hg for 15 min-i 3, 4, 5 - further exposure to oxygen). It is seen that a linear relation- ship is obtained between these two quantities for the freshly deposited film. It is concluded (in accordance with the J.Thomson theory, Ref.4) that freshly deposited germanium films are continuous and uniform right up to 10 mp, since the Ehange in the resistivity with thickness can be explained by the scattering of current carriers at the surface. This is confirmed by the fact that heatIng, oxygenatlon, etc. lead to a departure from the linear relationship. The mean free path of the current carriers in freshly deposited films of Ge was found to be approximately 100 ntp, which is in agreement with the value calculated from the mobility.

TITLE: Effect of oxygen on the electrical properties of an oxide cathode at low pressures PERIODICAL: Fizika tverdogo tela, v- 3, no. 5 , 1961, 1436 - 1444 TEXT: Insufficient attention has been paid in previous studies to the com- position of residual gases in vacuum apparatus. The authors have therefore conducted a thorough investigation, in which the sealedapparatus hgs repeat- edly been filled with oxygen and evacuated to pressures 10-6 - 10- mm Hg. The gas residue has been analyzed by means of an cmegatron. First of all, two peaks have been observed at m - 16 and m u 32, accounting for 94% of the total amount. Comparative measurements with the 600 mass analyzer by G. Ya. Pikus have shown the m - 32 peak to be higher. A small nickel tube filled with barium peroxide served as an oxygen source. Two 3P thick plati- num probes were introduced into the oyide layers which had a thickness from 60 to 1OOg - In addition to the cathode current, the measurements comprised conductivity, thermo-emf, and other electrical parameters. The cathode cur- Card 1/ 3 S/181/61/003/005/016/042 Effect of oxygen B136/B201 rent was measured at normal cathode temperatures with exponential pulses (f = 1 cycle), and at higher temperatures in d-c operation. Resistivity was determined from the potential drop between probe and core, depending upon the cathode current. The cathode temperature was determined by a calibration curve and by means of a thin thermocouple. Experiments have shown that both conductivity and thermionic emission current change almost in parallel and without delay during poisoning and reduction, i.e., almost allthe oxide layers participate in both processes. Two mechanisms are re- ferred to for an explanation; firstj the oxygen is adsorbed on all exposed and fully developed grain surfaces of the oxide-layer, and splits into atoms, whereby the negative surface charge of the grains is augmented; this is accompanied by a decrease of the work functicn, and, consequently, of all other electrical parameters as well. Secondly, the diffusion of the oxygen ions or atoms into the grains, which is directly proportional to their surface concentration,-reduces the number of oxygen vacancies which may act as donor centers. Taking account of diffusion providos an explan- ation for the experimental-fihdings. N. D. Morgulis, Correnponding Member AS USSR, is thanked for his interest in the work.

The investigated material Pe, Ag, Au, Ge, and KCI) was sprayed in wedge form upon a base within the ex- perimental device at a vacuum of about 5 x 10-8 mm of Ug. The thickness of the wedge was computed at each point and controlled by means of an MII-4 micro- i interfdrometer. The relations of effective depth to energy of quanta are shown in Table I (see Enclosure 1). It is concluded that the observed results may'be' explained if it is assumed that the effective depth is associated with the mean free path of fast photoelectrons generated within the target.

The temperature dependence of the electric conductivity 0~ oxides and halide compounds of the second group elements in the temperature rangre of 250 to 9000C was measured. The polycryptalline camples were prepared by pressing and subsequent ba!-ina in the air. The measurements were carried out in vacuum with direct current in wea' fields (2-3 to 75 v/cm) at a pressure of p - 10-~Mm of mercury column, Pla-tin electrodes were evaporated onto Card 1/3-, the samples. It appears that at high temperatures the Electric Conductivity and Lat~ice Energy of Compounds '' SOV/57-28-lo-14/4o of the bletals of the Second Group of D.I.lAendeleyev'B System electric conductivity of sintered oxides of second group metals decreases with an increase of the lattice energy, whereas the activation energy increases. Identical phenomena were also observed with other compounds. The specific electric conductivity of the second Group metal oxides, of the calcium-, strontium-, and barium fluorides, and of the calcium-, strontium-, and barium chlorides varies as the atomic volume of the metal, the polarizability of the cation, the decrease of the point of fusion of the compound, the dissociation energy and the magnitude of the isobaric potential. Hence the most simple compounds of the second group elements exhibit, besides the modification of the principal thermochemical features, a variation of the specific electric conductivity, which is governed by definite rules. In the range of low temperatures the activation energy of all compounds is considerably deficient of that in the range of hiCh t-emperatures and lies within the limits of 0.15 +;Q 0-58 eV.

Seriya fizicheakaya, v- 29, no. 11, 1965, 2055-2058 TOPIC TAGS: ferroelectric material.,','.sofid solution, barium, lead, calcium, titanate, Curie point, lattice parameter ABSTRACT: The authors have dejermined the Curie points of 17 barium titnnate-rich solid solut'ions of the bariwTFkitanatd'?- leae4tanate - calciwVtitanate system; the study was undertaken in view of the technical importance of the materials and the discordanceof the available data on them. Uniform mixtures for synthesis were ob- tained by spray-drying solutions of barium, lead alcium, and titanium nitrates. The resulting powders were roasted for 2-3 hours at 10C001c, compressed into 20 mm dia- .meter 1.5-1.8 mm thick disks, and sintered at 1260-13400C for 1-2 hours. Specimens for which the water absorption was less then 0.55% and the porosity less than 2-3% were selected for investigation. The selected specimens were analyzed, x-ray powder photographs were recorded, and their Curie points were determined within 20C by di- Card 1/2 L 7846-66 ACd NR, AP5028119 electric constant measurements. It was found that the Curie point increased with do- creasing.barium content.when either the calcium content, the lead content, or their ratio was held constant. When the barium content was hold constant the. Curie point increased with increasing lead content. Th 'e variation of the Curie point with compo- sition in the region of relatively high calcium content differed from that found by McQuarry (J.Amer-Ceram. Sec., 40, No. 2, 35 (1957)) and T.Ikcda (J.Phys.Soc. Japan, 3, No. 4, 335 (1958)), the present measurements giving the higher Curie points in this region.-, The solid solutiors with the higher Curie temperatures had unit cells with lareer volumes and, in agreement with the findings of McQuarry and Ikeda (loc.cit. supra) , higher degrees cf lattice tetragonality. The increase of the Curie temperature with increasing calcium, decreasing barium, and constant lead content contradicts the current opinion that 1heCuric temperatures of ferroelectrics with the perovskite structure are increased by increasing the volume and polarizability of the ions at the A-sites in AD03 6rystals. The discrepancy between the present results and those ob- tained by other authors with single compounds and binary systems is obviously to be explained by the fact that the laws governing the behavior of three-component systems containing A-type ions with different electronic structures are more complex than those applicable to binary systems. The discovery of these lawn will require further -investigation. Orig. art. has: 5 figures and 1 table. SUB CODE: SS, EK SUBM DATE.: 00/ REF: 003 am MW: 006 Card.

Doklady, v. 170, no. 1, 1966, 38-40 TOPIC TAGS: partial differential equation, boundary value problem, Fredholm equation,' integral equation ABSTRACT:' The following equation is studied Y(Y - 1)u XX + UYY = 0 in a specially constructed mixed region containing intervals of the lines of degene- racy y = 0 and y = 1. A boundary value problem connected with this equation is formu- lated and the solution sketched. It is shown that the problem of the existence of a solution reduces to the solution of a system of singular integral equations which may be reduced to a Fredholm equation of the second order, and that the solution of the boundary value problem may, after the Fredholm equation is solved, be constructed by solving Trikomils singular problem.

In Fig.1 the results of three series of measurements are shown. Tho initial portion or the curve corresponds to the ~-.-phase of the hydrogen-palladium solid solution; a horizontal portion of two-phase region follows,,,/ and the last portion rises steeply and corresponds to the ,'-phase of the solid solution.

The concentrations of hydropn_dis�olved in palladium remained lower than those at; 78'JC at the sQmo pressures. It follows that the bydrogen-palladima system had not reached equilibrium as the solubility of hydrogen in pal:Ladi= must increase with drop in temperature. There is 1 figure, and 4 references of which 2 are Soviet and 2 English. SUBMITTED: September 2, 1957 Card 2/2 SOV/120-59-1-44/50 AUTHORS:Nakhutin, I. Ye., Smirnova, N. M. TITLE: TFoduction of Pure xenon (Polucheniye chistogo ksenona) PERIODICAL: Pribory i,tekhnika eksperimenta, 1959, Nr 1, p 149 (USSR) ABSTRACT: A method of separating the hydrocarbons present in xenon is described. The elimination of the hydrocarbons was done by employing a highly active reagent which is prepared by depositing a layer of copper oxide on a surfade of silica gel. The reagent was placed in a short quartz tube (having a length of a few cm), and dehydrated at a. temperature of 3000C. The tube was then heated to ?OOOC-, and the xenon to be purified was passed through it. The device operated as a chromatographic column in that the change of colour of the reagent after the reaction permitted the observation of the C. front forming in the column. A preliminary filling of the column by xenon was done very slowly. Subsequently, the xenqn was passed in a continuous stream, at a rate of about 102/cm'hr, through the heated column and through another two colilmns operating at the ambient temperature. The other two colilmns captured the carbonic acid and the water vapours which formed during the oxidation of the hydrocarbons. After the operat- ion the column was regenerated at 6000C. By the above method Card 1/2 it was possible to obtain a spectrally pure xenon; the lines SOV/120-59-1-44/50 Production of Pure Xenon of hydrogen and o;-4gen could not be detected nor were the molecular spectra of hydrocarbons present, he method can be used for the purification of other rare gases. The authors express their gratitude to N. A. Teterina for carrying out the spectral analysis, There are no figures or references. SUBMITTED: February 15, 1958.

For the measurement of emission, Kr35 was filled in a plexiglass cylinder with an aluminum foil bottom. The yield was determined from the ratio k = N IN,9 where N , N are, respectively, Y Y Y 0 the numbers of 517 kev gamma quanta and of 0 particles emitted per unit time in the solid angle 0.
