Abstract
Silicon crystal surfaces with adsorption of (sub-) monolayer Au have been one of the most popular targets of research, because of the variety of beautiful ordered structures. The atomic arrangements, electronic band structures, phase transitions, Schottky-barrier property, surface electronic transport, electromigration, surface alloy phases, physics of one-dimensional metals, have been intensively studied by using Au/Si surface systems. Here, I introduce some results mainly from my group, showing some general physics obtained by this particular system.
