Abstract
Avalanche multiplication in In0.53Ga0.47As has been determined from photomultiplication measurements over the temperature range of 20 - 300 K for a series of p-i-n and n-i-p diodes. A negative temperature dependence is observed in the avalanche multiplication of In0.53Ga0.47As at electric fields over 200 kV/cm, contrary to the positive temperature dependence of collector multiplication previously observed in InP/In0.53Ga0.47As heterojunction bipolar transistors. Based on the photomultiplication measurements on p-i-n and n-i-p diodes, the temperature dependence of the electron and hole ionisation coefficient from 20 - 300 K in In0.53Ga0.47As is also examined.
