摘要：

Detailed structural studies of the growth of Fe on Au(111) have resolved the long-standing controversy about the nature of the structural phase change in the Fe/Au system. It has been thought that the first few layers of Fe on Au in this orientation grew as fcc. Here we show that the first few layers of Fe grow epitaxially on Au to form a rotated, strained face-centered structure. Subsequently the entire Fe layer relaxes via two distinct lattice distortions into bcc Fe.
