Temperature dependence of breakdown and avalanche multiplication in In0.53Ga0.47As diodes and heterojunction bipolar transistors [PDF]
, 2003 The avalanche multiplication and impact ionization coefficients in In/sub 0.53/Ga/sub 0.47/As p-i-n and n-i-p diodes over a range of temperature from 20-400 K were measured and shown to have negative temperature dependence.

High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit [PDF]
, 2011 High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to

Thermal profiles within the channel of planar gunn diodes using micro-particle sensors [PDF]
, 2017 The paper describes the use of a novel microparticle sensor (~3 μm diameter) and infra-red (IR) microscopy to measure the temperature profile within the active channel (typically 3 μm length and 120 μm width) of planar Gunn diodes. The method has enabled
