Abstract
Using the four-point probe method,we studied in sit tt the surface conducti vity of submonolayer Au/Si(100) and Au/Si(111) system. Electrical measureme nts showed that surface phases act as an additional conductivity channel. T he value of conductivity of this channel depends on the structural and elec tronic properties of the surface phases. Destruction of the surface phase o f atomically clean silicon by adsorbed Au atoms reduces the conductance of the substrate.
