SYNCHROTRON-RADIATION STUDIES ON METAL SEMICONDUCTOR INTERFACE ELECTRONIC-STRUCTURES/

Some progresses of the photoemission study on metal/semiconductor inte rfaces with synchrotron radiation at NSRL are reviewed in this paper. The possibility that the magnetic ordering exists in the ultra-thin ov erlayer of Mn on semiconductor surface is proposed. The formation of i nterface for Sm/Si(100)2x1 and its thermal evolution have been investi gated. For alkali and alkali-earth metal doped C-60 the doping effect and the interaction between doping and C-60 have been studied. Finally , the interface formation and the band offsets of Ge/ZnS(111) and Ge/Z nSe(100) are discussed in the text.
