Abstract
Minority carrier traps in n-type Ga1-xAlxAs (x = 0.25 and 0.30) grown by the organometallic vapour phase epitaxy process have been investigated by minority carrier transient spectroscopy (MCTS). Hole traps with thermal activation energies of Ev + 0.35 and 0.48 eV and a deeper centre have been observed in GaAs and at Ev + 0.20, 0.26, 0.44 and 0.78 in GaAlAs. The electron and hole capture cross-sections of these centres have also been measured.
