Recently,it has been indicated that graphene nanosheet can emerge as an alternative,unique two-dimensional plasmonic material that displays a wide range of extraordinary properties.It is promising to fabricate graphene/QD nanocomposites by considering the excellent plasmonic properties of graphene and the photoelectronic properties of QDs.It has been indicated that the graphene can act as different roles in the photoluminescence of the hybrid nano structures.

将硅和锗驱动到拓扑绝缘体相

拓扑绝缘体具有绝缘的体带和类金属的边缘态和表面态.其能带可以由Z2 拓扑不变量来刻画.我们从理论上证明了在这类体系中外电场控制自旋的可能性[1-5].在本报告中,我们研究了拓扑绝缘体中电子的动力学过程,提供了一个关于边缘态/表面态物理起源的简明图像,并讨论了电子震颤等过程.和普通绝缘体中非常不同的是,自旋向上和向下的电子会向相反的方向偏转,并在样品边缘处形成边缘态.利用电场同时可以有效地实现和控制

低维复合界面光伏器件研究

从科学基础研究与应用技术开发的角度出发,要提高太阳能电池的效率,必须从以下三个方面寻求突破[1,2]:1)实现太阳能电池对太阳光全光谱的吸收(陷光效应);2)增强光子转换成电子的效率(光电效应);3)改善光生载流子的输运和提高电极采集的能力(光伏效应).围绕这三个关键问题,我们从薄膜太阳能电池的关键界面入手,提出新型的低维复合界面结构与模型,研究该新型界面结构与陷光、光电效应及光伏效应的相关性.
