摘要：

Intra-row diffusion of Au atoms in the Si(111)-(5x2)Au reconstructed structure has been observed by using high-temperature scanning tunneling microscopy. Loosely bonded Au atoms. which are arranged with 2(n + I)a spacings at room temperature, diffuse in the twofold direction at higher temperatures among adsorbed sites arranged at 2a intervals. These diffusing Au atoms seem to be thr reason there is a nonintegral number of Au atoms in the (5x2) unit cell.
