带间Light Absorption系数的Lifshitz尾部

Lifshitz tails for the Interband Light Absorption Coefficient

W. Kirsch, M. Krishna

摘要:

在本文中,我们考虑了各种模型的带间光吸收系数。我们表明,在光谱的上、下边缘的状态密度的Lifshitz尾行为意味着类似的行为在适当的能量ILAC。在对应于态密度内部带边的某些点上也表现出Lifshitz尾性质。

英文摘要:

In this paper we consider the Interband Light Absorption Coefficient for various models. We show that at the lower and upper edges of the spectrum the Lifshitz tails behaviour of the density of states implies similar behaviour for the ILAC at appropriate energies. The Lifshitz tails property is also exhibited at some points corresponding to the internal band edges of the density of states.
