论文摘要
我们在Rashba旋转轨道相互作用的情况下呈现了带电粒子在潜在步骤中的传播和反射概率电流的理论和数值计算结果。通过不同的动能和入射电子角度或屏障高度，与隧道和电子反射相关的不同特征通过自旋间通道电子间电子隧道和反射揭示。这些独特的特性进一步伴随着具有相同动能但在不同的自旋轨道状态下的反射与自旋相关电子对的自旋量子干扰。预计这种独特的特征将在Spintronics和量子计算设备中引起许多应用。
We present both theory and numerical-computation results for the transmission and reflection probability currents of a charged particle across a potential step in the presence of a Rashba spin-orbit interaction. By varying kinetic energy and angle of incident electrons or barrier height, different features associated with tunneling and reflection of electrons are revealed by inter-spin-channel electron tunnelings and reflections. These unique properties are further accompanied by spin-state quantum interference of either a reflected or transmitted pairs of spin-correlated electrons with the same kinetic energy but in different spin-orbital states. Such distinctive features are expected to give rise to a lot of applications in both spintronics and quantum-computation devices.
