Microplasma characteristics in InP-In0.53Ga0.47As long wavelength avalanche photodiodes

Abstract
Characterization of microplasmas has been performed on InP‐In0.53Ga0.47As avalanche photodiodes using electron induced current and low‐temperature cathodoluminescence measurements. Microplasmas are shown to be associated with a local increase of the electric field resulting from doping fluctuations which are tentatively associated with impurity segregation at crystal imperfections.
