摘要
本文应用一种计算无序系统中电子本征态的方法,求得了含有2000个粒子的无序系统中电子局域态的分布,并结合态密度、计算误差进行了分析讨论。所得结果表明,在不同的能量范围内局域态的分布不同,分布可遍及整个系统,且与无序度有关。
The distribution of electronic localisetion n the disordered system of 2000 particles is obtained by a new method for calculating eigenvector. The distribution is discussed with the density of states and the calculation error. The result shows that the distribution is changed with the energy, the distribution area may cover the entire system, and the distribution is affected by the disorder degree.
