Abstract: | Conclusions The electronic properties of Au/Si interface are investigated with a homemade ballistic-electron-emission microscope. The
spatial distribution of Schottky barrier height is detected. Irreversible changes of ballistic transmittance of local interface
with typical size of a few hundred of angstroms in diameter are observed by raising the tip voltage temporarily. Ballistic-electron-emission
spectroscopy indicates that the electron transmission probabilities are reduced significantly inside the modified region,
which is attributed to the Au-Si intermixing and other chemical reactions occurring at the interfacial layer stimulated by
the injected energetic hot electrons. |
