High-temperature surface metallization of Si(100) is observed at T > 900 K by high-resolution electron-energy-loss and ultraviolet photoemission spectroscopy. Metallization takes place well below the incomplete surface melting temperature and is consistent with the Si dimer dynamics, characterized by an instantaneous symmetriclike dimer configuration. The surface free carrier concentration in the metallic phase has been evaluated, reaching (at 1170 K) the same order of magnitude of the surface dimer density.

Abstract

High-temperature surface metallization of Si(100) is observed at T > 900 K by high-resolution electron-energy-loss and ultraviolet photoemission spectroscopy. Metallization takes place well below the incomplete surface melting temperature and is consistent with the Si dimer dynamics, characterized by an instantaneous symmetriclike dimer configuration. The surface free carrier concentration in the metallic phase has been evaluated, reaching (at 1170 K) the same order of magnitude of the surface dimer density.
