Chemical vapor deposition and photoluminescence properties of Zn-DOPED GaAs

Abstract
An experimental study of the VPE growth of GaAs at 1 023 K from the AsH 3-HCl-Ga-H 2 system yields for the dependence of the hole concentration on the technological parameters : p (300 K) ∼ p HCl·p-1GaCl·p1/2AsH3·p Zn. It is concluded that the process takes place under non equilibrium conditions. The PL intensity depends distinctly on the preparation conditions but does not fit a simple model
