摘要：

The energy required to remove an atom from semiconductor surfaces is calculated using a Greens-function approach. Contrary to intuition, we find that, in some cases, less energy is needed to remove an atom from the nearly full surface than from a nearly empty surface. The results are explained in terms of the relative energies of anion and cation dangling bonds, and the charge transfers between them. The deducted effective pair-interaction energies and their effects on surface morphology and growth perfection are discussed. © 1990 The American Physical Society.
