Abstract
Selective epitaxial growth of GaAs on GaAs and In0.49Ga0.51P surfaces, using photo-enhanced organometallic chemical vapor deposition, was in vestigated. The growth rate dependence on illumination intensity, trim ethylgallium partial pressure, and temperature is reported. In-situ pa tterning and three-dimensional shaping during growth of GaAs/InGaP bur ied heterostructures, are demonstrated. The experimental results are i n good agreement with a simple model, in which the decomposition of ad sorbed trimethylgallium is assisted by surface recombination of photo- excited free carriers.
