STABILITY AND ELECTRONIC PROPERTIES OF VACUUM-EVAPORATED AMORPHOUS METALLIC Au-Ge ALLOY FILMS

摘要

The existence and stability of amorphous metallic Au-Ge alloys prepared by co-evaporation under ultra-high vacuum are discussed. Their optical properties are analysed in terms of a Drude and an interband contribution. Occurrence of sp-d hybridization is inferred.
