教育背景

1988年毕业于北京师范大学获硕士学位,2003年毕业于湖南大学获博士学位。

2004年至2006年在复旦大学表面物理国家重点实验室从事博士后研究。

1997年晋升为副教授,

2001年晋升为教授。

学术兼职

科研项目

近年主持国家自然科学基金项目、湖南省自然科学基金项目、教育厅重点项目等项目研究。

近几年代表性研究成果:

(a)理论预言新的整流机制并被权威实验证实。理论预言在分子整流器中扮演最重要角色的给体-受体型有机分子存在新的整流机制— 反向整流(Appl. Phys. Lett., 98, 013503(2011)),此后这一结论被美国劳伦斯伯克利国家实验室(Lawrence Berkeley National Laboratory)新合成的给体-受体型分子的实验测量所证实(ACS Nano, 5(11), 92 56(2011))。

(b)提出Cn/A-σ -D/Cn新型杂化结构。研究发现其整流特性及NDR现象有明显的奇-偶特性,且整流比大幅提升,同时呈现出阈电压低、整流范围广的特点(Adv. Funct. Mater. 23, 2765 (2013))。

(c)发表APL封面文章。对有机分子器件电子输运稳定性问题进行了深入研究, 获得了规律性结论,这对于了解和理解分子器件输运稳定性的内在机理提供了新的视角,Appl. Phys. Lett选为封面文章进行重点推介报道 (Appl.Phys.Lett. 97(18),183105,(2010) http://apl.aip.org/resource/1/ applab/v97/i18 )。

(d) 提出全碳sp-sp2新型杂化结构。研究发现其具有传统p-n结二极管的整流特性,如近线性的正偏压I-V特性(金属性)、极小的负偏压漏电流(绝缘性)、极低的阈电压、大偏压范围整流等。同时发现其构造的三极管具有非常高的电流放大特性(Sci.Rep. 3, 2575 (2013))。
