Surface electromigration of Au on Si(001) studied by REM [link]Paper  doi  abstract   bibtex   
Surface electromigration processes of a Au deposit on Si(001) surfaces were studied by reflection electron microscopy (REM). A patch of the Au deposit was observed to move in the direction opposite to the current. When the current was fed in the [110] direction anisotropic growth of domains of the Au adsorbed structure along the [11̄0] or [1̄10] direction only on the Si(001)2 × 1 surface terraces in the anode side area to the patch was observed. In this case Au atoms migrated not only on the adsorbed surfaces but also on the substrate Si(001) surfaces. When the current was fed in the [010] direction Au domains spread continuously in the [110] and [110] directions. A c−2 × 18 structure which has not been reported before was formed by the electromigration.
