Abstract

A transition from a fractal to a nonfractal surface behavior of thin gold films deposited at different substrate temperatures has been observed by scanning tunneling microscopy. At $T_{s}$ =298 K, columnar deposits are formed whereas at 673 K a faceted deposit is obtained. Data can be used to test the validity of different growth models, including surface atom relaxation.
