摘要：

We present theoretical evidence that Schottky-barrier heights may, for certain types of interfaces, be far more sensitive to interface geometry than previously suspected. We have identified two classes of diamond/metal interface orientations, one of which leads to Schottky-barrier heights of order 1 eV, the other to barrier heights that are very small or zero. This striking difference can be traced to details of the gap-state band structure that arise from different bonding mechanisms, for which the precise atomic geometry plays a crucial role.
