A mixed method of molecular dynamics and tight binding is applied to a Si-cluster surrounded by SiO(2) in order to study an influence of interfacial states on the band structure of the Si cluster. As a result, it is found that intrinsic interfacial states invade the band gaps of Si and SiO(2) from the conduction band, which may suggest that the Si dot surrounded by SiO(2) sounds metallic due to the interfacial states. This feature occurs while the size of the Si dot is less than at least 4 nm.
