A heterojunction device composed of p Ge‐ v ZnSe‐ p + GaAs‐ p + Al x Ga 1− x As is proposed for efficiently converting infrared radiation of 1.5‐μm wavelength into radiation of 0.9‐μm wavelength. Conceptually, this is a possible approach to the development of a high‐efficiency...
Radiosity and temperature distributions and transmission probabilities are found for annuli of various geometries which are irradiated by ``black'' uniform radiation at one end. The geometries considered are R i ∕ R o = 0.1, 0.3, 0.5, 0.7, and 0.9 with L ∕ R o − R i )= 0.1, 0.5, 1.0, 5.0,...
A new technique is described in detail which can be used to profile boron impurities in almost any substrate to a depth of a few microns. It uses the reaction 10 B ( n , 4 He) 7 Li to convert boron atoms to monoenergetic α particles which are detected after they leave the target. The technique...
The amplification characteristics of a surface shear wave mode in GaAs has been investigated and shown to be closely approximated by the bulk wave theory, where trapping effects are included. At a frequency of 205 MHz, relative electronic gains from 35–50 dB∕cm have been observed.
High‐resistivity GaAs double‐injection devices have recently been investigated by Ferro and Gandhi. They found a sublinear ``current saturation'' in oxygen‐doped n ‐type material but not in chromium‐doped p ‐type GaAs, causing them to refute an interpretation by the relaxation‐case...
The energy distribution of the electron emission originating from Ta☒Ta 2 O 5 ☒Au thin‐film devices has been measured utilizing a 127° electron energy spectrometer. The shape of the distribution can indicate the losses and electron temperatures associated with conduction through thin...
When a single‐crystal substrate of silicon is covered with evaporated gold and heated at relatively low temperatures (100–300°C) in an oxidizing atmosphere, a silicon‐dioxide layer is readily formed over the gold layer. The mechanism and factors controlling this low‐temperature oxide...
An asymptotic theory for the admittance of two collinear antennas is developed. The antennas can be of unequal lengths, and the feedpoint locations are practically arbitrary. The only restrictions are that the radii must be equal and small; while the smallest feedpoint‐end distance and the...
The amplitude and phase of space potential oscillations are readily measured with a hot electron‐emitting probe. Measurements performed in a collisional cesium plasma, unstable to drift waves, are presented and compared with linear drift‐wave theory.
