论文摘要

在接下来的论文中,我们调查了二维S/Ti(S表示超导体和Ti-拓扑绝缘子)的临界温度$ T_C $行为,其与接近诱导的Ti表面的平面内螺旋磁化。 $ T_C $的计算是使用Matsubara Green功能技术中USADEL方程的一般自洽方法执行的。我们表明,螺旋磁化的存在导致临界温度的非单调行为,这是拓扑绝缘体层厚度的函数。

In the following paper we investigate the critical temperature $T_c$ behavior in the two-dimensional S/TI (S denotes superconductor and TI - topological insulator) junction with a proximity induced in-plane helical magnetization in the TI surface. The calculations of $T_c$ are performed using the general self-consistent approach based on the Usadel equations in Matsubara Green's functions technique. We show that the presence of the helical magnetization leads to the nonmonotonic behavior of the critical temperature as a function of the topological insulator layer thickness.
