Abstract

The interface properties of hydrogenated amorphous carbon films (a-C:H) on Si and GaAs substrates have been studied by in-situ photoelectron spectroscopy measurements. The a-C:H films have been deposited by direct ion beam deposition. Distinct differences in the interface formation have been observed during film depositon on the two substrates. The data clearly reveal a decomposition of the GaAs at the interface which can be related to the reduced adhesion of a-C: H on the compound semiconductor substrate.
