High quality epitaxial germanium (Ge) was successfully grown on In0.53Ga0.47As substrate using a metal-organic chemical vapor deposition tool. The valence band offset ΔEV between the Ge layer and In0.53Ga0.47As determined by high-resolution x-ray photoelectron spectroscopy was found to be 0.5 ± 0.1 ...
