| 摘 要： | 本文同时计入表面原子库仑积分和交迭积分的改变对有限一维AB型离子晶体表面电子态的影响,采用紧束缚近似和原子轨道线性组合(TB—LCAO)方法,导出了体系的本征方程。讨论了交迭积分改变时体系的表面态存在条件和表面态能级,并给出了波函数的一般表达式。

SURFACE STATES OF A FINITE 1—D AB MIXED CRYSTAL WITH LATTICE RELAXATION |
| |
| Abstract: | The effects of the surface lattice relaxafion and the surface perturbation potential on the surface states of a finite 1—D AB mixed crystal are calculated by using TB—LCAO method. The energy eigenquation is presented. The energy levels and the wave functions of the surface states are discussed. |
