研究领域

低维体系由于表面/界面效应、量子受限效应、和量子相干效应所表现出的新奇物理性质。主要研究内容为利用扫描隧道显微镜（STM）和电测量手段对石墨烯和其它二维原子晶体的物理性质进行研究。我们课题组长期坚持石墨烯的物性研究主要基于如下两点原因：首先，石墨烯中电子除了自旋这一内秉自由度，还拥有子格赝自旋和谷赝自旋自由度，可以实现基于电子多自由度的新奇量子物态；其次，石墨烯只有一层原子厚，非常稳定，制备技术成熟可控，便于对其结构进行表征和调控，构建理想的模型体系，实现一系列新奇量子物态。基于此，我们发展了一系列方法（包括转角、应变结构、堆垛层错、缺陷、衬底等）来调控石墨烯的电学性质，在石墨烯中实现了一系列新奇量子物态，并在纳米尺度、单电子精度上实现了对石墨烯中自旋和（子格、谷）赝自旋的探测与调控。具体介绍如下: 1）石墨烯中平带的实现及其新奇强关联量子物态的探测与调控：通过魔转角双层石墨烯、应变石墨烯、ABC三层石墨烯、垂直外磁场等在石墨烯体系中引入平带，率先利用扫描隧道显微镜（STM）测量了这些平带中的强关联物态，包括轨道铁磁态、自旋和谷极化的金属态、自旋和谷极化的铁磁态等； 2）石墨烯中谷电子学研究：首次利用磁场和赝磁场共同作用在单层石墨烯中单电子精度上实现了谷极化和翻转的探测与调控；利用磁场调节双层石墨烯中准粒子的Berry相位，实现了谷极化的探测与调控；首次利用STM直接观察到了双层石墨烯中能传输谷极化电流的AB-BA畴界； 3）石墨烯中原子尺度下自旋和子格赝自旋研究：首次直接观察到石墨烯中单原子缺陷磁矩的证据，并在原子尺度内实现了对其磁性的调控，观察到了三种不同的磁性量子态。通过单原子缺陷在石墨烯中产生原子尺度子格赝自旋涡旋，并证明赝自旋涡旋的角动量可反映体系的Berry相位。
