Abstract

Multilevel Si-doped GaAs epitaxial layers with abrupt interfaces can be grown using a single AsCl₃:SiCl₄ liquid doping source with a constant doping flow rate in an AsCl₃/H₂/Ga chemical vapor deposition system. Doping variations are achieved by adjustments in the HCl to H₂ partial pressure ratios. The H₂ is injected between the source and substrate to vary the HCl partial pressure. Si concentrations in these layers vary inversely as approximately the cube of the H₂ to HCl partial pressure ratio for a fixed SiCl₄ inlet flow.
