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.

该项目旨在开发金刚石的氢终止表面作为碳基自旋电子学的新半导体平台。它将建立在最近的实验进展，已显示金刚石拥有一个二维（2D）的孔为基础的系统与强自旋轨道耦合。作为一种具有独特自旋特性的半导体，表面导电金刚石相对于其他二维材料如石墨烯和拓扑绝缘体具有相当大的优势。这些独特的属性将被利用来实现新的半导体器件架构的自旋使用电场的操纵，并为新的自旋输运现象和准粒子激发在超导体-超导体界面的研究。
