Abstrakt: The means by which deep traps in annealed low temperature molecular beam epitaxy grown GaAs are responsible for its remarkable semi-insulating and short lifetime properties has been the subject of much discussion. For example, while low dc bias and high speed phototransient measurements can be explained as consequences of a homogeneous trap distribution in the non-stoichiometric material, experiments demonstrating the presence of electrically active precipitates must be dealt with. The study below, which is numerical, concludes that a consistent argument based on the presence of electrically active precipitates, coupled to a surrounding distribution of traps, will account for much of the observed experimental phenomena.
