从理论和实验两个方面对ＣｄＴｅ（１１１）表面碱金属吸附的电子结构特性进行了研究．实验结果表明碱金属Ｋ在ＣｄＴｅ（１１１）表面吸附是Ｃｄ替位吸附，它影响了ＣｄＴｅ（１１１）表面的表面态分布，产生了费密钉扎现象．在理论方面，首先采用线性糕模轨函数（ＬＭＴＯ）方法对ＣｄＴｅ（１１１）表面的Ｋ吸附电子结构特性作了研究，得出了与实验符合的结果．对碱金属在ＣｄＴｅ（１１１）表面的吸附电子结构特性系统对比研究表明ＣｄＴｅ（１１１）表面的碱金属吸附特性不仅受碱金属原子序数的影响，而且与碱金属原子的内层电子组态有关
The electronic structural characteristics of CdTe (111) surface alkali metal adsorption were studied theoretically and experimentally. The experimental results show that the adsorption of alkali metal K on the surface of CdTe (111) is Cd substitution adsorption, which affects the surface state distribution of CdTe (111) surface and leads to Fermi pinning phenomenon. In theory, the K-adsorbed electronic structure of CdTe (111) surface has been studied by LMTO method. The experimental results are in good agreement. A systematic comparative study of the electronic structure of the adsorbed alkali metal on CdTe (111) surface shows that the adsorption of alkali metal on the surface of CdTe (111) is not only affected by the atomic number of alkali metal, but also related to the electronic configuration of the inner layer of alkali metal atom
