TITLE: Some Optical Proportion of Solid Solutions of Indium

PERIODICLL: Fizika tveTdogo tela, 1960, Vol. 2, No. 1, pp. 50 - 51
TEXT: The authors found a varying 11 olubility in the systems
InAs-In 3Te3and InAs-In 2Se3 (Refs. 1,2), which is explained by struc-
tural and -energy factors (Ref. 3). When studying the forbidden zone
in alloys of the systems considered, they determined AE values for dif-
ferent compositions, according to the absorption edge. The method's ap-
plied to the synthesis and homogenization of the alloys had been de-
scribed already earlier (Refs. 1-3). The absorption spectra were re-
oorded with the aid of the infrared spectrophotometer OKC-14 (IKS-14).
Fig. I shows the absorption curves of InAs, In 2Se,9 as well as
41nAs.In2Se 39 and 21nAs-3In2SeY The longwave absorption edge shifts

regularly from one binary component to the other. This is indicative of
the fact that the width of the forbidden zone of the alloys has inter-
mediate values between 4E - 0-3 ev and AE - 1.2 ev. Fig. 2 shows ab-
sorption curves for InAs, InAs.In 2Te 39 and InAs.3In2Te3. Also in this
caae, the absorption edge shifts regularly from InAs to In 2Te 3' Re-
sults of optical measurement confirmed the possibility of obtaining,
substances in which the width of the forbidden zoney compared to the
AE values of the binary initial components, has intermediate values.

Since all specimens showed electron-type conductivity, it is assumed that a sharp
increase of the concentration is connected with the origination of a greater
number of donor levels on account of Se atoms which substitute As. Measurements
of X have shown that if small amounts of In2Se3 are added to InAs, )( decreases
more rapidly than 5. The temperature dependence )(of the alloys is in a satis-
factory agreement with Pierls' theorg. Measurements of the coefficient of heat
expansion show that in the 150 - 650 C temperature range its.value increases

TEXT: Systems of InP, InAs, InSh with NIS2, InIS0. IniTc., were studied in order to prepare solid solu-
tiom bawecti indium compounds of the type A(III)B(V) and A2(111)B3(VI) under an argon atmosphere. The
products were analyzed by X-ray diffraction, thermally and mciallographically. In such systems solid solutions, 1A
over a wide rangern or new compounds were formed. The temperature dependence of electrical conductivityW
and of the Hall effect were also studied. Solid solutions with the zinc blcndc structure and semiconducting
properties wcre found in the InP-ln,'SC3, and InAs-1112SC3 ond In As-ln2-Tc3 systems. A new compound
ln4surc3 was found having NaCl structure with a lattice parameter of 6.123A and semiconducting properties.
New fields of application for the semiconducting InAs solid solutions on the basis of their electric, magnetic,
and optical characteristics are suggested. There arc 5 tables.

ABSTRACT: The solubility of Ga2S3, Ga2Se3, and Ga2Te3 in GaP was investigated, and
the conductivities, Hall constants, and photoconductivities of GaP and some of.the
GaP-Ga2S3 solid solutions were measured. The materials were produced by fuzing and
vibrating the purified components in evacuated qiiartz ampoules. The sampled were
ground to size with carborundum, and electrical contact was provided by vacuum de-
posited silver films cr spark welded platinum conductors. The system (GaP)3x(Ga2-
S3)1-x formed solid solutions with the zineblende structure for x between'l and 0.3;
Ga2S03 formed solid 'solutions with GaP in all proportions; and Ga2Te3 and Gap provud

compounds. The lattice constants of the solid solutions varied linearly with compo-
sition; that of the sulfide system was 5.45 R for x = 1 (GaP) and 5.32 R for x =
= 0.3. The conductivity and Hall constant of n-type GaP were measured at tempera-
tures f rom 80 to 3000K. The. carrier concentration was 2.2 x 1016 cm-3, and the mo-

ory of D.J.Howarth and E.H.Sondheimer (Proc.Roy.Soc.219A,53,1953) indicated that
most but not all of the scattering was due to polar lattice vibrations. The Hall
constant decreased with increasing temperature -much more rapidly at temIx-,ratures a-

purity levels, the activation energies of which were found to be 0.02G and 0.48 eV.

terials of the (1nSb)X(jriTe)l_x system were mpasured at temperatures from 80 to
6500K. The conductivities and Hall constants of the solid solutions were nearly in-
dependent of temperature, and the thermal emf,,s increased slowly with increasing
temperature. The conduction electron concentration increased sharply from 7 x 1016
cm-3 for x = 1 (InSb) t0'9 x 10-18 cm-3 for x =' 0.999 and remained nearly constant
at that value as x was reduced to 0.80 (there was no marked change in the electri-
cal properties at the appearance of the second phase) . The electron mobility de-
creased somewhat less sharply from approximately 48 000 cm2/V scc for x = I to 1500
cm2/V sec for x = 0.97 and also remained nearly coAstant as x was further decreased.
All the alloys of the (InSb)X(InTe)l-x system with I ~_~ x !? 0.27 were found to ex-
hibit n-type conduction, and those with 0.25 -a- x, p-type. Thus, a transition from
p- to n-tyde conduction can be achieved in these alloys by altering the compositioa.

296K. The measurements were made at 80 and 296K. Both tempera
tures,,
speaks of photoconductivity were observed at approximately 44 and 51
nm, and In addition, regular oscillations were observed at wavelengths'!
lower than 0.40 ~L, attributed to strong interactions between the non- i
equilibrium caririers and longitudinal optical pbonons. The results
bare qualitatively interpreted from the point of view of the band
.structure of GaP. 'The complicated nature of this band structure makeg
,a quantitative analysis difficult. The reason why the oscillations
were not observed at room temperature is that the over-all photo-
onse decreases with increa3ing temperature, owing to the intensi-'~
.resp
fication of thermal capture, reduction in the diffusion length of
.the electrons and increased rate of surface recombination. The
relative roles of the direct and indireettransitions are estimated.

ABSTRACT: The melts were made in an apparatus consisting of a vertical
quartz tube (d--22 mm) in which a Si bar was placed vertically on
two pins rotating at I to 50 rpm. The inductor (d=25 mrn, height
4-6 mm) creating the zone was fed from a 5-kv generator work-
ing at 4 mc. The rate of motion of the bar relative to the inductor
was 0.5-10 cm/hr. A vacuum of the order of 1-10-5 mrn Hg was
created in the quartz tube. The specimen was heated to 7000C by
current passing through it. Elongated bars 15-20 cm long and
10- 13 mm in cross section, and specimens of Si iodide in the
form of tubes 8- 16 mm. in diameter, filled with pieces of Si, were
Card 1/2 used for the melts. The quartz tube was replaced after 3 to 5

Employment of Floating-zone (cont)
passes due to the growth within it of a film that screened the field. When an
asbestos cylinder rv5 cm long was mounted on the tube for purposes of heat
insulation.in the vicinity of the inductor, checking and crumbling of the film
diminished. The course of the melt was followed visually after the firstpass
and thereafter by instruments. *Single crystals were obtained from the super-
heated zone after 4 to 7 passes when the rate of motion of the zone was 3-6
cm/hr. The employment of single-crystal seeding and rotation of the speci-
men facilitates production of single crystals. It was established that 6 to 8
passe5 of the zone make it possible to purify acid-washed Si until it is Spec-
trally pure for 60-80% of the total length of the specimen, but the resistivity
of the specimen rises little as this occurs, viz. , from 0.05 to 0.08 ohm/Cm.
Floating zone refining of a s~pecimen of Si with introduction of Ta 182 into the
final zone makes it possible to purify the specimen of Ta to 10-5-10-8% after
I to 7 passes of the zone. The Ta is concentrated in the final portion of the
bar. The concentration of Fe59 after the first pass drops to 1o-4%., and the
Fe is concentrated in the final zone. Si iodide yielded single crystals that
were chiefly of the p type and had a resistivity of 15-40 ohm/Cm.

tion was carried out in order to synthesize a new luminescent heterocyclic compound
with high efficiency as an admixture to plastic scintillators, having a pronounced
fluorescence in the range of about 4,500A . Compound (I) is.prepared by condensa-

110 ml alcohol, 1.8 g acetophenone and I ml 10% NaOH added, the turbid solution
left to stand at room temperature for two days, and afterwards the precipitated
(I) is filtered off, washed, dried, and recrystallized with acetone. The final
product (II) is prepared by dissolving 4.2 g (I) in 700 ml of an alcohol/benzene
mixture (6.: 1), subsequent addition of 2.1 ml freshly distilled phenylhydrazine,
2.1 ml conc, HCl.and the condeqs~ation is carried out at 90 - 950C during 28 h

TEXT: The oxidation of hexaethyl ditin (I) with oxygen (II) in n-nonane
solution at concentrations of I ranging from 10 to 100 mole% has been
studied. The oxidation rate of I is described by a first-order equation
according to the concentration of I, and is independent of the pressure
of II within the range of 300-500 mm Hg~ In the temperature range of
60-900C, E(act.) is 19.5 kcal/mole. 0.55 mole of diethyl stannic oxide,
0.62 mole of triethyl stannic oxide, and 0.12 mole of acetaldehyde are
formed per mole of oxidized I. Water was found qualitatively. The
oxidation of I is not catalyzed by addiTion of 13.2 mole% of triethyl
lead oxide. Addition of 2,6-di-tert-butyl-4-methyl Dhenol lowers the

Nine patients were followed up for 7 to 30 manths after vagotomy. Neutral gastrion was
diminisned, but humoral secretion was normal., except that tne gastric juice s.Wded low
acidity. Defective emptying of the stomach may cause stagnation, even after 21 years.

Diarrhoea was cantion. In general tho results of vagotomy corresponded to these obtained
w*Lth experimental animals.
