Abstract:
A method of making a stable oxidized film structure, comprising the steps ofproviding a substrate with a clean surface, wherein said substrate comprises a material selected from the group consisting of Si, Ge, and combinations thereof; depositing a metal on said clean surface at a temperature of at least 750Â° C. under a vacuum in which the pressure is less than 1Ã—10âˆ’8 Torr to form a metal-substrate compound layer on said clean surface with a thickness of less than one monolayer; and oxidizing said metal-substrate compound layer to form a monolayer of an oxidized film on said substrate by exposing said metal-substrate compound layer to a gas consisting essentially of oxygen at a pressure in the range of 1Ã—10âˆ’8 to 1Ã—10âˆ’6 Torr at a temperature in the range of 25Â° C. to 200Â° C.
