主要科研内容简介

1)已完成的研究内容。

从理论上系统地研究二维范德瓦尔斯材料及其形成的异质结分别在层间偏压、局域电势和磁场调控下的能带结构、拓扑量子态的输运性质以及拓扑相变行为。研究发现:石墨烯/六方氮化硼范德瓦尔斯异质结在局域电压或者横向门电压作用下呈现出半金属性并会经历半导体-半金属-半导体相变,以其构建输运器件可以实现完全自旋极化输运;在局域势作用下异质结可以实现半导体到金属相变,而在局域势和磁场的共同作用下,其层间电导具有平台状的特性,这与无磁场的情况完全不同;石墨烯/氮化硼三层异质结中可以通过调节局部势和库仑排斥势来实现半金属性;对于嵌入氮化硼中石墨烯纳米带平面异质结构,其带隙随石墨烯纳米带宽度的变化而变化,通过调控局域势可以实现半导体-金属相变。这些结果对于我们深刻地理解二维范德瓦尔斯异质结的输运性质有着重要意义,同时在磁隧道结和自旋极化输运器件设计中具有潜在应用前景。

2)拟进行的研究内容。

探索二维纳米材料的量子输运性质并运用各种手段进行有效的量子调控使之能够应用于新型电子和自旋器件是当前急需解决的关键问题之一。我们将进一步系统地研究石墨烯/六方氮化硼和石墨烯/过渡金属二卤属化合物平面异质结分别在电场、局域势和磁场调控下的能带结构和电磁输运特性,尤其是自旋极化输运特性和隧穿磁阻效应。给出通过电场调控能隙的方案并寻找可能出现的拓扑相;阐明体系的输运机理并提出调控输运性质的方案,并据此设计电子、自旋输运器件。
