ABSTRACT: The published literature contains information on the investigation of spon-1
taneous, stimulated, and coherent radiation of GaAs p-n junctions pertaining to t e
characteristic radiation parameters as a function of the current for diodes with or
,without resonators. The purpose of the present article is to compare the dependences
of the maximum energy hvM and the half-width 6 of the fundamental radiation band on the
current density through a single p-n junction with and without a Fabry-Perot reso-
nator. The authors studied diodes In which the p-n junctions were V~talned Iby dif-
fusion of zinc in To-alloyed n-CaAs with electron concentration 7-IOl-3-10 hcm-3;
the area of the p-n junction =10-3cm. The current through the diode and the spectral,
distribution of radiation Intensity were measured. It was found that bv,, starting

from the lowest current densities a/cm2), increases with increasing current and
then becn is practically independent of the current. The dependence of 6 on current
density is given for small current densities (5--70 a/cm2). It is concluded from the
results presented that the primary narrowing of the spectrum occurs as a result of
population inversion at the rarefied states which are responsible for the secondary
narrowing of the spectrum, i.e., beyond the conventional stimulated and coherent ra-
diation with maximmis energy -1.47 ev. The "tails" in the forbidden zone are
probably the rarefied states responsible for the primary narrowing of the spectrum.

ABSTRACT: In an experimental investigation of epitaxial p-n GaAs junctions,telluriuu-!
doped n-type and zinc-do~ed p-type GaAs was used. The electron concentration in the
n-type GaAs was 5.5 x 10 7-2.4 x 1018 cm-3; the hole concentration in the p-type GaAs
was 1.5 x 1018-2.4 x 1019 cm-3. The specimens were oriented along the (100) plane
and the epitaxial p-n junction was prepared from the liquid phase by a method descrRed
elsewhere (H. Nelson, RCA Rev., 24, 603, 1963). The dislocation density near the p-n
junction in the epitaxial layers did not exceed that in the wafer and was 104 cm"2.
The Fabry-Perot cavity was formed by the cleaved (110) surfaces,and the electrical

contacts were made of indium. The residual resistance of a diode with an area of
10-3 CM2 was less than 0.1 ohm. Laser action at room temperature was achieved with
30-nanosec current pulses. An FEU-22 photomultiplier recorded the optical output.
The threshold currents were determined from the dependence of intensity on current.
The p-type GaAs specimens with hole concentrations of 2.4 x 1019 cm-3 and a mobility
of 50 cmz/v-sec lased at 90001 at threshold currents of 1.5 x 105 amp/CE2. Investi-
gachns sere also made cfspecimens in which the epitaxial layer, doped with zinc and
partly compensated by lead, wa grown on a tellurium-doped GaAs substrate with an
electron concentration of 9.5 : 1017 cm-3and a mobility of 2400 cm2/v.sec. 7hese
lased at room temperature at 9010 X at currents of 3.8 x 105 amp/CM2 and at 8910
at currents of 4.7 x 105 Mp/cm2 and up. The power per pass of p-CAAs lasers was

ABSTRACT: The results of an experimental investigation of GaAs electron-photon
transistors(R. Rediker et al., Proc. 1763, 51, 1, 218) at 77 and 293K are
reported. The transistors were made from Tjjdoped n-GaAs. Source meterial parameters:.
electron concentration, 7 x 1O17 - 5 x 10 per am3; mobility, 1800-3200 cr&2/v seell
dislocation density, 10000 per cm2; p-n-p structure was produced by Zn diffusion;
plate thickness, 300 u ; base thickness, 100-200 w ; p-region thickness, 50-100 u
Collector current vs. collector voltage characteristics (for 0-100 amp/cm2 ezrdtter
current) and collector current vs. emitter current characteristics are shown. The
emitter-collector current transfer ratio was found to increase from 0-05 to 0.075
with the collector voltage increasing from 0 to 8 v, at 77K. At room temperature,
th,.j transfer ratio amounts to 1/20-th of the liquid-nitrogen ratio. When the emitter

current increases from 0.1 to 0.5 amP, the power gain decreases from 12 to 4 and
the voltage gain, from 350 to 60 (at 77K). The estimated total quantum yield of
photons Is 0.1 at 77K. Desirability is noted and ways are indicated for making
the electron-photon transistor a practical amplifier. Orig. art. has: 4 figures

ABSTAACT: 7his is a continuation of earlier work (Frr v. 8, 712, 1966), where it was
obser%*ed that the spectral distribution of the quontum yield of the internal pbotoef-~-l
fect in the short-range region is connected with singularities of the band str`ucturle
of GaAs. The present work extends the investigation to InAs. The InAs p-n junctions
were obtained by diffusion of Cd in n-type material with electron dei-isity (0.5 - 1)
X 1017 cnr3 and were produced at a depth of several microns. The hole concentration
in the illuminated surface of the swple was approximately 1010 cnr3. Several p-n
junctions illuminated ficim the n-side were also tested. 7he long-wave part of the
spectral character-istic of the jurwtion was plotted with the aid of a ZMR-2 mono-
chrmator, and the measurements at higher energies were by the procedure described in
the ewlier paper. 7he measurements showed a narrcw long-save photosensitivity peak,

connected with the change of the absorption coefficient near the edge of the ground-
state band, followed by a mgion of weak variation, a faster grmoth at %0.7 - 1 ev
photon enerV, a rieversal followed by minimun near 3.2 ev, and a renewed gmwth at
higher energies. Mm results am shown to be connected with the variation of the
quantum yield of the internal photoeffect as a result of secondary icniwticn. 7he
threshold mmW of the photon, starting with shich the quantum yield begins to gmwt
is found to be 0.7 - 0.8 ev at 293K and 0.9 - 1 ev at 100K, in agremant with theo-
retioal cala-lations by others. 7he various secticna of the spectruin axe interpreted
m this basis, so it is indicated in the conclusion tat the actual quantm yield
may not be as lmqp as what foLlam f:rom theoretical acmiduutions, since account
must be taken of the priol~ty mtios; of the difftrint electsude UUNSWAM. MIX
