个人简介

       刘畅,南方科技大学物理系副教授。刘博士的研究兴趣主要是利用角分辨光电子能谱(ARPES)和其他谱学技术揭示拓扑材料,热电材料和高温超导体的新颖电子特性,以及石墨烯及其相关结构中的奇异电子行为。他的研究小组还掌握了材料的生长技术,例如利用助溶剂法,化学气相转移法(CVT)生长单晶材料,利用分子束外延(MBE)方法生长单晶薄膜材料等。在拓扑材料领域,他的工作发现了磁性拓扑绝缘体中的无能隙拓扑表面态,三维Dirac半金属中的费米弧表面电子态以及第一个拓扑晶体绝缘体。在热电材料领域,他的工作揭示了一系列基于SnSe的高性能热电化合物的价带信息。他在Science, Nature Physics, Physical Review X, Physical Review Letters等杂志上发表研究论文约50篇,被引5000次左右,H-index为29(谷歌学术)。
