工作成果
:
首次實現了寬禁帶半導體GaN表面上磁性超薄膜的分子束外延生長和垂直磁各向異性。成功製備出具有巨大Rashba自旋軌道劈裂表面態的Ag量子阱薄膜並觀測到Rashba劈裂表面態與量子阱態的強烈的相互作用，實驗證明了這種作用的自旋選擇性及其引起的量子阱態的自旋劈裂。實現了Bi2Se3系列三維拓撲絕緣體薄膜的逐層外延生長，首次觀測到三維拓撲絕緣體相對表面態的雜化導致的能隙打開。2010年獲中科院物理所“科技新人獎”。2011年獲中國科學院盧嘉錫青年人才獎。共發表論文約二十餘篇，其中Phys. Rev. Lett. 5篇（第一作者2篇），Nature Physics 2篇 （通訊作者1篇）。曾在美國物理學年會、美國磁學與磁性材料會議（3M會議）等國際會議和研討會上做邀請報告。
