ABSTRACT: This paper was read at the Scientific Meeting of the
Technical Sciences Section,, Ac.8c. USSR devoted to the
40th anniversary of the October revolution. The main
trends in the field of vei-j high frequency electronic
apparatus are discussed.. Brief descriptions are -,iven
of some of the apparatus d.eveloped and manufactured in
the Soviet Union, namely, the fc,)lloviing; "spinatron tube"
(travelling WELve tube with. a centrifugal electrostatic
focusing of the electron fluxes), for which the deDendence
of the coefficient of amplification of the vave len-th
is graphed in Fig.4, p.108; metallo-cerainic triodes;
reflex klystrons. Zusmar.ovskiy, S,A. and bis team
developed a klystron for linear accelerators of charged
particles, the pulse power Of Which exceeds 20 MW and it
was shown that still more powerful klystrons can be
Card 1/1 developed. There are 10 figure.-, and 8 references, all of
which are Russian.

ABSTRACT It was the purpose of this investigation to study a sub-
stance which can be used for the construction of a thermo-
electric battery as well as to investigate the question of the
possible heat conduction processes in semiconductors. First it
is shown that the difference N - ko -.>,-a is that part of heat
conductivity which is due to the transfer of thermal energy
by current carriers. According to prosent theories thermal
resistance increases with temperature. At a certain value
T 0 heat-resistance tends towards zero. Above 2000 K

heat resistance deviates considerably from the rectilinear
temperature-dependence and becomds smaller. Therefore

TEXT: Two n-type and four p-type germanium samples were-examined (Table 1).
The thermocouples provided to measure the temperature were soldered to
small tin balls applied to the lateral surfaces of the aamples in vacuo.
It was shown by the experimental results that there in a difference in the
.thermal conducti*ity of n- and p-type germanium between 80 0K and 3400K
(Fig. 1). This phenomenon is explained by the assumption that the additional
heat resistance of n-type germanium is due to dissolvod gases such as
0 , and N.. This is confirmed by the high a:bsorption coefficient at
2' H2
wavelengths ranging between I' and 10 Ii. The thermal conductivity coefficient

calculate the additional thermal conductivity Ax on the assumption tnat
it is due to heat transfer by electromagnetic riLdiation. Calculated values
of the absorption coefficients haVe the same order of magnitude as the
values established experimentally (Table 2). A comparison of values found
for heat resistance with those given by otherauthors is shown in Fig. 3.
From this it follows that 1/w depends linearly on T for a not excessively
pure germanium within a wide temperature range (from 80 to 11000 0K). The
absorption coefficients of two samples were measured by G. B. Dubrovskiy;

n-type PbSe samples were examined. Their carrier concentrations (Table)
varied from, 3-3-W7 to 9.6*1019 Cm-3. Four of tbe n-type samples were
polycrystalline, and the rest were single crystals. The thermal
conduc'tivity and the therino-emf of all samples, on the one hand, and the
temperature dependence of electrical condi7~ctivity and the Hall constant,
on the other, were measured simultaneously (by Ye. D. Nensberg). Fig. 1
shows thermal conductivity as a function of temperature; the curves of
all samples show similar (exponential) courses, and the value for A is
nearly equal to 2. Figs. 2 and 3 show the thermo-emf as temperature

samples had a very low thermo-emf (20 - 160 gv/deg). Fig. 4 shows the

TEXT: Ye. D. Devyatkova had studied the heat conductivity of PbTe in 1956
(ZhTF, V. 27, no. 3, 461, 1957) and found a deviELtion from the theoretical
dependence I/K17T in the temperature range 250-4,500K, I A, being the thermal
resistance of the crystal lattice. The object of the work was to study this
effect in a larger temperature interval (90-6001)1,') and extend the investiga-
tion also to PbSe. Fine crystalline sintered samples and large crystals
were used. They had been obtained by Ye. D. Nenl3berg by cooling the melt of
stoichiometric composition. All samples were annealed at 600-9000K. The ap-
paratuses for the measurements of heat acnductivity were those described:

from the linear course is connected with the degree of purity. An additional

TITLEs Effect of halogen impurities on the thermal conductivity of
lead telluride
PERIODICAL: Fizika tverdogo tela, v. 3, no. a, 1961, 2298 - 2309
TEXT: The thermal conductivity of PbTe has been studied already several
times, however, the effect of various impurit-5es has hitherto not been
considered. Only T. L. Kovallchik and Yu. P. Maslakovets studied the
effects of various impurities on the electrical properties of PbTe; they
demonstrated that halogen impurities greatly increase the free-electron
concentr.ation. Samples that contain impuritles in the form of PbBr 2 (or
PbCl 2' Pb 12 ) also have a high absolute carrier mobility. Thermal conduc-
tivity, electric conductivity, Hall constant, and thermo-emf were measured
in 14 pairs of single and polycrystalline PbTe samples with halogen impu-
rities as well as in PbTe + 1% PbSe and PbTe 4, 1% SnTe solid solutions.
The samples were produced from pure elements (lead 99.99% pure). All

PbBr2 + Pb, and PbI 2 + Pb were obtained by the ordinary cermet method.
The solid solutions were produced by melting together the initial subst
in a stoichiometric ratio. Prior to the meat3urements the samples were
annealeds the single crystals at 3000C, the polycrystals at 6000C (for
several hours). After examination of their homogeneity, the measurements
were made. The PbTe samples alloyed with -,bI 2 were the most thoroughly

siderably decreases which may be due to the large phonon scattering cross
section of the halogens. Goldsmid tried to explain the anomalously
large cross section by assuming that the halogen atoms are located in
interstitial sites. Othex studies made by Goldsmid (in Bi 2Te 3) and
Kovallchik and Maslakovets indicate that they are located in the lattice
sites and occupy the sites of tellurium. Hence, the reason of their
large phonon scattering cross section remains unexplained. According to

TEM The exponent r in the relation l(T,F,) = 1 o(T ),,,r where I is the
mean free path of electrons, S the energy, characterizes the scattering
mechanism. According to theory, r - 0 in the scattering of electrons
from acoustic lattice vibra~lons which characterizes the covalent type
of bond. In the scattering from optical vibrations r - 1/2 ( T< 9) and
r = 1 (T> 9) which is characteristic of the ionic bond. For scattering
from imj~Arity ions r - 2. Since the scattering mechanism of ~fie carriers
in PbTe has hitherto not systematically been studied, the authors studied
it via determining r by measuring the electron contribution to the therm3l
conductivity and the carrier mobility as depending on temperature. They
demon3trated that in PbTe scattering from accustic lattice vibrations
predominates (r - 0). This result had been obtained already by

TEXT: As-pure NaCl and KC1 crystals have stable values of thermal
conductivity they can be used for calibrating experimental arrangements
or for comparison with MeELsured thermal conductivity values of other
crystals in the alkali-halogen group. NaCl and KC1 crystals must be
perfectly pure (thermal conductivity is changed by moisture and impurities)
and must either be stored in dry places or be annealed before measurement.
The crystals were grown from a melt of X4 (KhCh) salts, annealed through
6-8 hours at 6000C and then slowly cooled to room temperature. Th~ measur-
ing method is that employed by Ye. D. Devyatkova et al. (FTT, 2, 738, 1960).

thermal conductivity was measured on the "All setup of Ye. D. Devyatkova, A. V.

ABSTRACT: This is a continuation of earlier research by the authors (m v. 6. 43oD,
1964) on the thermal conduct;ivity of rare-earth metals and their compounds, and is
devoted to a separation of the electropic and lattice components of the thermal can-

thermal conductivity, resistivity, and thermal emf itnd their temperature dependence
it is deduced that an appreciable fraction of the total thermal conductivity is due
to the crystal lattice. The temperature dependence of the lattice component can be
attribie.;ed to the presence of two scattering mechanisms, phonons by phonons and
phonons by conduction electrons. The law carrier mobility observed in the experi-
ments is due essentially to strong electron-phonon interaction. The presently al"Lil-
able data on IATej, We., and LaS are summarized in it -table. The authors thwk A. Is
