Voltage pulse modulation of photoluminescence in p-GaP

View publication

Abstract

A substantial enhancement of the photoluminescence of p-GaP and a shift to shorter wavelengths have been observed at 27 and 4°K, after the application of a voltage pulse of sufficient magnitude to raise the current appreciably above the value extrapolated from low fields. The current rises abruptly above a critical voltage. The observations are explained in terms of a model based on impact ionization of holes bound to isolated acceptors. © 1968 The American Physical Society.
