摘要：

Metals such as Au deposited on graphite substrates are found to migrate very easily when biased in scanning tunneling microscopes. Depending upon the him thickness and the tip voltage, a hillock surrounded by grooves or a hole surrounded by hillocks with a height of similar to +/-10 nm and a lateral dimension of similar to 100 nm are formed. The mechanism of these surface-modification phenomena is discussed in light of electro- and thermomigration.
