Abstract
Desorption of Bi and Ag deposited on Si(100) surfaces has been investigated by Auger electron spectroscopy for heat treatment in an oxygen atmosphere. Bi was desorbed from the Si surface at substrate temperature Ts of 450∼500°C, and Ag was desorbed at Ts of 510∼560°C. The RHEED patterns for Ag overlayers before the desorption suggest that Ag atoms rearrange in the [011] direction.
