Recently,the subject of the metallic surface states of the topological insulator (TI) has attracted great attention in condensed matter physics.Topological insulators in two or three dimensions have insulating energy gaps in the bulk,and gapless edge or surface states on the sample boundary that are protected by time-reversal symmetry.

磁传感器广泛应用于计算机读出磁头、电子罗盘、GPS导航、车辆探测系统等,其核心技术就是巨磁阻效应,该效应的发明人获2007年诺贝尔物理奖.通常巨磁阻材料是用磁性金属材料制备的,半导体材料虽然也可以有磁电阻,但是数值太小,没有应用价值.
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
早在上世纪七八十年代,在探索如何在硅基半导体上制备好的金电极时,就开始研究硅在金薄膜中扩散的性质.近十年,当人们开始转向纳米器件时,发现金硅颗粒是硅纳米线生长的很好催化剂[1].然而,催化剂在不同温度和气氛环境下的行为研究,无论从基础研究的角度还是从应用的角度,都是有意义的.
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.
We investigate the competition between the spin-orbit interaction of itinerant electrons and their Kondo coupling with local moments densely distributed on the honeycomb lattice.We find,by a slave-bos
In order to study the gap function of the newly discovered skutterudite superconductor PrPt4Ge12(Tc=7.9K),we have measured the London penetration depth λ(T) and specific heat of the single crystalline
Graphene,an atomically thin made material made only carbon atoms arranged in a hexagonal lattice(honeycomb lattice)was isolated,several reviews on the physics of graphene are already available in lite
We investigated the multiferroicity of the polycrystalline samples Gd1-xTmxMnO3 (0≤x≤0.3) (GTMO) by measuring the structural,magnetic,dielectric and polarization properties.It is found that the polari
Although the mechanism of superconductivity in the cuprates remains elusive,it is generally agreed that at the heart of the problem is the physics of doped Mott insulators.A crucial step for solving t
