摘要：

Sapphire (0001) substrates were annealed at 1000 degrees C for 12 h in air to obtain flat surfaces with a step-terrace structure. Au films were deposited on the substrates using the Molecular beam epitaxy (MBE) method, at various substrate temperatures. The surface morphology of the films was observed by means of atomic force microscopy (AFM). A quasi one-dimensional alignment of Au particles was partially prepared along the steps at the substrate temperature of 620 degrees C. On the other hand, an atomically flat An thin film was obtained at the low substrate temperature of 130 degrees C. A C-60 monolayer was obtained by re-evaporating the C-60 molecules deposited on the Au films, which was confirmed by X-ray photoelectron spectroscopy (XPS).
