主要科研成果:
1.石墨烯费米能级自适应特性系列研究：国际首次从实验和理论全面、系统研究石墨烯/半导体界面的接触特性，证实半导体的表面态和石墨烯费米能级的自适应，二者共同决定界面接触势垒。并进一步探讨了界面态密度、半导体载流子浓度等因素对势垒的影响，该系列两篇论文分别于2012年发表在美国AIP的Appl. Phys. Lett.（被Virtual Journal of Nanoscale Science & Technology 收录）和2014年的J. Appl. Phys.上，目前总引用已达58次。
2.CVD生长石墨烯与GaN半导体的欧姆接触特性研究：国际首次从微观视野研究了石墨烯/半导体欧姆接触形成机制，并从理论和实验证实石墨烯褶皱方向对于欧姆接触形成的调控机制。该论文于2014年发表在AIP的Appl. Phys. Lett.杂志。
3.半导体衬底石墨烯的微区迁移率：国际首次报道半导体表面石墨烯微区迁移率的测量方法。创新性的发展了一种KPFM和C-AFM结合对以半导体为衬底的石墨烯微区载流子迁移率进行测量的方法。该论文于2018年发表在美国APS的Physical Review Materials杂志，该杂志目前每年全球仅收300篇论文。
主要技术研发成果:
1.单次扫描KPFM测量局域光电性质技术：将测量50-100 nm 的分辨率提高到10 nm 以下，而且测量速度增加一倍。为华中科大唐江课题组提供的测试结果，作为关键数据在Nature Photonics发表。
2.扫描近场光电多功能探针系统的研制：该系统实现了SPM/SNOM/Raman/PL/EL/ PV系统集成，在波长300-900 nm，可测量纳米尺度局域表面光电压和光电流谱，空间分辨率小于20 nm。
3.微区力、电、磁、液体环境等测量技术的应用研究：精研SPM高级测量技术，覆盖材料、化学、生物等多学科领域，获得载流子浓度、pn掺杂、局域导电、磁畴分布、能带等信息，以及液体环境下对生物样品表面形貌。
4.参与国家标准《氮化镓单晶衬底表面粗糙度的原子力显微镜检验法》（GB/T 32189-2015）的研究和制定：本人为该国标第二作者。
