Abstract
The emission probability of Gamma electrons is calculated for the (100) and (110) faces of negative electron affinity GaAs. Together with previously published results for the other major faces ((1,1,1)A and (1,1,1)B) (Burt and Inkson, ibid., vol.9, p.43 (1975)) the data are discussed in terms of simple models to explain the calculated variation. The large difference between the experimental and theoretical results for the (110) face is found to have a ready explanation in terms of a microscopic model for the surface recombination velocity.Keywords
