摘要:

数值研究了Rashba自旋轨道相互作用对Matsubara和Toyozawa(MT)的n-杂质半导体中电子模型的影响。我们专注于分析的态密度(DOS)和逆参与比(IPR)的自旋轨道微扰态的MT组的能量本征态,以表征本征态相对于其扩展或本地化的性质。我们能够考虑的有限尺寸需要增强自旋轨道耦合强度,以获得有意义的微扰。IPR和DOS,然后研究作为增强参数的函数。

英文摘要:

We study numerically the effects of the Rashba spin-orbit interaction on the model of electrons in n-doped semiconductors of Matsubara and Toyozawa (MT). We focus on the analysis of the density of states (DOS) and the inverse participation ratio (IPR) of the spin-orbit perturbed states in the MT set of energy eigenstates in order to characterize the eigenstates with respect to their extended or localized nature. The finite sizes that we are able to consider necessitate an enhancement of the spin-orbit coupling strength in order to obtain a meaningful perturbation. The IPR and DOS are then studied as a function of the enhancement parameter.
