摘要：

Gold adsorption onto a Si(111)7 x 7 surface is studied in situ by Scanning Tunneling Microscopy (STM). Gold is deposited onto the Si(111)7 x 7 surface, kept at 500-degrees-C during the STM observation. The 5 x 2 structure grows at a step edge and expands towards both the higher and lower terraces. Si islands are also formed during the gold deposition. These phenomena are explained by the production and migration of excess Si atoms during the phase transition from the 7 x 7 to the 5 x 2 structure.
