摘要:

发展了一种直接在k空间求解杂质态Luttinger-Kohn方程的数值方法,并应用于计算铁磁(Ga,Mn)As基质中束缚空穴波函数。任意应变的铁磁锌半导体的能带结构的丰富性质产生了各种特征,这些特征对与活性杂质结合的价带空穴的详细形状具有直接影响。应变的作用进行了讨论的基础上明确计算的束缚空穴状态。

英文摘要:

A numerical technique is developed to solve the Luttinger-Kohn equation for impurity states directly in k-space and is applied to calculate bound hole wave functions in a ferromagnetic (Ga,Mn)As host. The rich properties of the band structure of an arbitrarily strained, ferromagnetic zinc-blende semiconductor yields various features which have direct impact on the detailed shape of a valence band hole bound to an active impurity. The role of strain is discussed on the basis of explicit calculations of bound hole states.
