一维纳米固体的电子结构

本文通过计算一维纳米固体模型的电子态密度,针对颗粒大小、颗粒界面无序度等物理量,讨论了一维纳米固体的电子结构。结果表明颗粒大小对电子能态结构影响较大,而颗粒界面无序度主要引起能带宽度和态密度大小的变化。 关键词：

ELECTRONIC STRUCTURE OF THE ONE-DIMENSIONAL NANOMETER SOLID STATE MODEL

The electronic structure of the one-dimensonal nanometer solid state model is discussed in terms of the grain size and the disordered degree of the grain surface by the computation of the density of electronic states. The result shows that the effect of the grained size on the electronic structure is great, and the disordered degree of the trained surface cause mainly the change of the energy width and the magnitude of the density of state.
