论文摘要
灰色锡作为一种拓扑量子材料吸引了更多的兴趣，该量子材料具有精确控制的组成，并且可以成为自旋设备的材料。但是，灰锡中的自旋动力学在很大程度上是未知的。在本文中，我们通过结合密度功能理论和紧密的模型来计算灰色TIN的拓扑表面状态，还提出了电磁学 - 量子力学混合方法如何通过元结构增强元结构中灰色TIN中的自旋极化光电流，这是最近经过实验性测量的。
Gray Tin is attracting much more interest as a topological quantum material, which has a precisely controlled composition and can be a material for spintronic devices. However, the spin dynamics in gray Tin is largely unknown. In this paper, we calculate the topological surface state of gray Tin by combining density functional theory and a tight-bind model, also propose an electromagnetics -- quantum mechanics hybrid approach on how to enhance with metastructures the spin polarized photocurrent in gray Tin, which was experimentally measured recently.
