Abstract
The surface structures of amorphous Zr65Al7.5Cu27.5-alloy films prepared by ultra high vacuum physical vapor deposition are investigated with scanning tunneling microscopy to identify the major surface mechanisms for amorphous film growth. A fourier analysis of the STM images shows that curvature induced surface diffusion and a non-smoothing surface mechanism is present. Numerical simulations using a Monte-Carlo and a continuum model which includes adatom concentration triggered surface diffusion as additional coarsing mechanism are in excellent agreement with the experimental results.
