Abstract
We report an oxygen-induced metastable ordered structure on a Si(001) surface. The c(4X4) structure is obtained after extensive annealing of a clean Si(001)-2X1 surface dosed with oxygen at room temperature. Th is c(4X4) structure appears only after the completion of the 2X1 struc ture, which disappears in the early annealing stage. The c(4X4) struct ure reverts back irreversibly to the 2X1 structure after the surface i s heated to above 720 degrees C. Possible structural models for the c( 4X4) reconstruction are discussed.
