| Research Abstract |
Recent experi ments found unusual behaviors of Schottky barrier, i.e., the energy-level difference between metal and nonmetal materials, which cannot be explained by previous theories. By using quantum mechanical calculations, this project has shown that such behaviors originate from the selective atomic bonding, the formation of compounds, and the segregation of impurities at interfaces, and has constructed a new generalized theory of Schottky barrier.
