Thermodynamic Analysis on Vapor Phase Epitaxy of GaAs by GaCl3 and AsH3 System

Abstract
A thermodynamic analysis of the VPE growth of GaAs using GaCl3 and AsH3 is described. It is shown that most of the GaCl3 converts to GaCl and HCl at about 650°C and that the growth of GaAs is possible by the GaCl3 and AsH3 system without using a high temperature zone. The experimental features of the system can be explained well by equilibrium model.
