摘要：

For the first time, a thick p-type GaAs layer was successfully grown by molecular beam epitaxy on a GaAs(0 0 1) substrate using Si as the dopant. A hole concentration in the range of 10(18) cm(-3) was achieved by a nonconventional growth method involving the supply of a few monolayers of Ga atoms together with the dopant (the As-4 cell was shuttered), followed by annealing in As-4 (the Ga and Si cells were shuttered). The repetition of this sequence led to a thick p-type layer as shown by Hall and photoluminescence measurements. (C) 1999 Elsevier Science B.V. All rights reserved.
