Abstract

Interface strength, chemical bonding, and O-K ELNES of Cu/Al2O3(0001) interface was calculated by using the first principles band structure calculations. The origin of the weakeness of the on-top configuration can be ascribed to be the strong anti-bonding interaction between the interfacial oxygen and the 2nd near neighbor Cu. It was found that the pre-peak feature of O-K ELNES is related to the chemical bonding of the interface.
