Surface doping of diamond: A new platform for 2D carbon-based spintronics

该项目旨在开发金刚石的氢端表面，作为碳基自旋电子学的新的半导体平台。它将建立在最近的实验进展的基础上，这些进展表明钻石拥有一个基于二维(2D)空穴的系统，具有很强的自旋-轨道耦合。作为一种具有独特自旋性质的半导体，表面导电金刚石相对于石墨烯和拓扑绝缘体等其他2D材料具有相当大的优势。这些独特的性质将被用来实现利用电场操纵自旋的新型半导体器件结构，并用于研究半导体-超导体界面上新的自旋输运现象和准粒子激发。

This project aims to develop the hydrogen-terminated surface of diamond as a new semiconducting platform for carbon-based spintronics. It will build upon recent experimental advances that have shown diamond to possess a two-dimensional (2D) hole-based system with strong spin-orbit coupling. As a semiconductor with unique spin properties, surface conducting diamond offers considerable advantages over other 2D materials such as graphene and topological insulators. These unique properties will be exploited to realise novel semiconductor device architectures for the manipulation of spin using electric fields, and for the study of new spin transport phenomena and quasiparticle excitations at semiconductor-superconductor interfaces.
