摘要：

We show that oxygen binds readily in a bridging site of adatom backbonds in the Si(111)7 × 7 surface. Furthermore, a well-ordered Si(111)7 × 7: O structure is stable in excess of 105 L O2 exposure at room temperature. Electron beam irradiation during dosing additionally leads to very rapid disordering of the surface. © 1990.
