Abstract

GaAs has been grown on (100) and (111) Si and GaP substrates by MOCVD during the same run at a substrate temperature of 550°C. The defect structure of the interface and the epitaxial GaAs layers has been analysed by transmission electron microscopy (TEM). Depending on the substrate type and orientation different defects and defect orientations were observed which can be attributed to different types of misfit dislocations and the thermal mismatch between the two materials.
