论文摘要
我们研究了磁性绝缘体与半导体 - 驱动器 - 磁性绝缘体混合结构中磁性绝缘体与半导体线之间的接近效应的影响。通过使用混合系统的有效模型执行自洽SCHR $ \ ddot {\ rm O} $ dinger-poisson计算,我们发现,与磁性超导性的出现一致的大型有效的Zeeman领域与磁性超导的出现一致,而在电线中,与磁性无磁性的磁性无磁性和超级构造的磁带层中的大量参数相关。我们表明,这种行为本质上是静电效应的结果,该效应决定了半导体 - 磁性绝缘体界面附近低能波函数的振幅。
We investigate the impact of electrostatics on the proximity effect between a magnetic insulator and a semiconductor wire in semiconductor-superconductor-magnetic insulator hybrid structures. By performing self-consistent Schr$\ddot{\rm o}$dinger-Poisson calculations using an effective model of the hybrid system, we find that large effective Zeeman fields consistent with the emergence of topological superconductivity emerge within a large parameter window in wires with overlapping layers of magnetic insulator and superconductor, but not in non-overlapping structures. We show that this behavior is essentially the result of electrostatic effects determining the amplitude of the low-energy wave functions near the semiconductor-magnetic insulator interface.
