表面效應(yīng)對slab模型的DOS的影響
|
|
在以slab模型計(jì)算表面的電子結(jié)構(gòu)時,一般會存在由于低維效應(yīng)導(dǎo)致的能帶變窄,但是看了很多文獻(xiàn)中都只是簡單提到,比如 "These differences in the contral layer DOS, which should approximate the bulk DOS if the slab were thick enough, are largelyy size effects due to the finite thickness of the slabs." 或者 "From the comparison of Figs.1a and 1b we can state that there is some decrease (of the order of 0.5eV) of the band gap width wich the increase of the slab thickness. The size effects and the surface effects manifest themselves better in the layer density-of-states plots." 我想查閱一些對這方面講述比較詳細(xì)的文獻(xiàn),即slab厚度的變小如何導(dǎo)致能帶寬度變窄的具體原理,求推薦文獻(xiàn),謝謝! |
