Abstract

Abstract In this paper, experimental data on the effect of light illumination on the 77 K mobility in four undoped n-type LPE GaAs samples are presented and discussed in conjunction with the μ-T curves for five such samples. It is shown that our experimental results are in agreement with the concept of a “mobility killer” and also provide evidence for space-charge scattering as its origin in n-type GaAs as suggested by Weisberg and Blanc in 1960.
