研究领域

""My research interests have been in the quantum transport of electrons in low dimensional systems, where quantum effects dominate the behaviors of electrons and in some cases, electron spins play an important role. These effects can lead to novel electronic properties. The current research mainly focuses on a recently discovered 2-dimenional material, graphene. Owing to its unique electronic structure, graphene exhibits exceptional properties that make it a promising material for the next generation electronics. My efforts concentrate on growing large size and high quality epitaxial graphene on SiC and studying its transport properties. The goal aims at making all-graphene meso- and nano-structures and exploring their potential application in electronic devices."""研究兴趣集中在低维电子体系在低温强磁场下的量子输运行为，以及对这些行为的量子调控。在低温、强磁场的极端条件下，电子的量子效应往往起决定作用，主导着其行为。同时，电子的自旋的作用也在特定环境下凸显出来。这时候系统可能表现出一些新颖的电子性质。\r
近年来兴起的材料之星石墨烯，是一种理想的二维电子气材料。由于其优异的电学性质和丰富的量子现象，不但在凝聚态物理和材料领域掀起了研究的热潮，也被看作是下一代半导体技术的一个强有力的候选者。在诸多制备方法中，碳化硅外延生长的石墨烯具有表面形貌原子级平整、晶格缺陷少、参杂浓度极低、迁移率高、可大面积生长以及无需转移衬底等突出优点。因此，它不但适于石墨烯中狄拉克电子的本征性质的基础研究，也在未来电子学应用中有光明前景。我的研究关注碳化硅上外延石墨烯的生长和物性研究，探索对材料的量子调控，并寻找利用这些调控手段实现新型量子器件的途径。"
