简介

　强如七布举负　研究方向:表面物理、半来自导体物理、自旋电子学、分子束外延、角分辨光电子能谱、扫描隧道显微镜

工作成果

　　:

　　首次实现了宽禁带半导体GaN表面上磁性超薄膜的分子束外延生长和垂直磁各向异性。成功制备出具有巨大Rashba自旋轨道劈裂表面态的Ag量子阱薄膜并观测到Rashba劈裂表面态与量子阱态的强烈的相互作用，实验证明了这种作用的自旋选择性及其引起的量子阱态的自旋劈裂。实现了Bi2Se3系列三维拓扑绝缘体薄膜的逐层外延生长，首次观测到三维拓扑绝缘体相对表面态的杂化导致的能隙打开。2010年获中科院物理所"科技新人奖"。2011年获中国科学院卢嘉锡青年人才奖。共发表论文约二十余篇，其中Phys. Rev. L360百科ett. 5篇(第一作者2篇)，Nature Physics 2篇 (通讯作者1篇)。曾在美国究殖境对级房鲜车守号盾物理学年会、美国磁学与磁性材料会议(3M会议)等国际会议和研讨会上做邀请报告。
