Abstract
A structural and mechanistic model for initial room temperature Fe epi taxy on Cu(100) is presented, based on scanning tunneling microscopy d ata. Changes in Fe atom attachment kinetics with coverage theta yield several growth regimes: Fe incorporation into the surface by atomic ex change with Cu (theta < 0.2), growth of first-layer Fe islands (0.2 < theta < 0.7), and simultaneous layer-1 and layer-2 growth (0.7 < theta < 2). These results reconcile qualitative disparities in previous int erpretations of experimental results.
