摘要

利用相对论线性增广柱面波方法计算了手性铂纳米管的电子和自旋性质。自旋轨道耦合引起了费米能区非相对论色散曲线的强烈分裂。上下自旋状态的自旋密度的巨大差异可以用来产生通过小管的纯自旋电流。在Pt (5, n2)和Pt (10, n2)两个系列中，(5,3)和(10,7)纳米管表现出最强的手性诱导自旋选择性效应。

Platinum Nanotubes Calculated Using Relativistic Cylindrical Wave Technique: Chiral Induced Spin Selectivity

Electronic and spin properties of chiral platinum nanotubes are calculated using the relativistic linear augmented cylindrical waves method. The spin-orbit coupling induces the strong splitting of nonrelativistic dispersion curves for the Fermi energy region. The large differences in spin densities of states for spins up and down can be used to create pure spin currents through the tubules. In the two series Pt (5, n2) and Pt (10, n2), the (5, 3) and (10, 7) nanotubes show the strongest chirality-induced spin selectivity effects.
