个人简历
李峰 教授1994/09-1998/07在吉林大学电子科学与工程学院进行本科学习,获得微电子学士学位。1998/09-2003/07年在吉林大学集成光电子国家重点实验室攻读博士学位,获得微电子学与固体电子学博士学位。2003/09-2004/12在以色列理工学院Tessler教授课题组进行博士后研究。2005年2月回到吉林大学工作,被聘为副教授,2008年10月晋升为教授,2011年聘为博士生导师。
研究兴趣

(1)基于新的发光原理的有机发光材料与器件:比如由我们首次提出并实现的双重态激子发光的有机电致发光器件(OLEDs),开发与之对应的中性共轭自由基发光材料。

(2)由分子间弱相互作用诱导的有机共轭分子的自组装过程,并研究自组装的纳米结构的光电性质。

(3)有机半导体材料与器件所特有的磁场效应,并利用磁场效应作为工具,研究有机光电器件内的物理过程。


荣誉奖励
2009年教育部自然科学一等奖 “新概念有机电致发光材料” 排名第五。
《凝聚态物理学进展》2012-2014 年 编委
