Abstract
Carrier trapping times in different parts of chemically profiled sampl es of nonstoichiometric GaAs obtained by molecular beam epitaxy at low substrate temperatures or by As or Ca ion implantation were determine d by using temporally resolved photoluminescence measurement. No short ening of the trapping time by the presence of metallic precipitates an d other extended defects was evidenced. (C) 1996 American Institute of Physics.
