LASER RECOMBINATION TRANSITION IN p-TYPE GaAs

Abstract
Data are presented (77°K) showing that laser transitions to either the valence band edge or to the acceptor, or both, are possible in a specific impurity concentration range (2 × 1017−1018/cm3) in GaAs:Zn and GaAs:Cd. These data are observed on a low‐loss crystal structure that is pumped uniformly.
