Emission from the (1,1,0) face of negative-electron affinity gallium arsenide

Abstract

The transmission probability for electrons incident on the (1,1,0) face of GaAs activated to negative electron affinity has been calculated for electrons at the same energy within the X and Gamma minima. The two transmission probabilities obtained are found to be both fairly small, suggesting that multiple reflection within the surface space charge region plays an important role in this system.
