Properties of low-dimensional metals fabricated on solid surfaces

由于电子-电子、电子-晶格和Rashba型自旋-轨道相互作用，在固体表面制备的低维金属通常表现出特殊的性质。在本研究中，我们在半导体表面的低维金属上发现了各种类型的Rashba自旋极化电子态，这将是未来自旋电子技术的基础。我们还发现在硅表面的铟单层膜中的金属-绝缘体相变是通过赝一级相变进行的。

Low-dimensional metals fabricated on solid surfaces often exhibit peculiar properties due to electron-electron, electron-lattice, and Rashba-type spin-orbit interaction. In this research work, we have discovered various types of Rashba spin-polarized electronic states on low-dimensional metals on semiconductor surfaces, which will be the basis for coming spintronic technology. We also found that a metal-insulator phase transition in an indium monolayer on silicon surface undergoes via pseudo-first-order transition.
