Relationships between Electronic Structure and Stability of Metallic Glasses.

Abstract

Amorphous Au-Ge and Ag-Ge alloy films were prepared by co-evaporation on low-temperature (15-20K) substrates under ultra-high vacuum for Ge concentrations between 20 and 40 at.%. Changes in short-range order have been observed by room-temperature electron diffraction experiments for Ge concentrations larger than 30 at.%. The d.c. electrical resistivity and the optical properties of the as-deposited amorphous metallic alloys are examined in detail as a function of composition. The Drude model with a constant relaxation time is found to reproduce the low-energy optical data satisfactorily.
