报告摘要： 有机-无机复合钙钛矿材料，由于其较大的吸收系数，较长的载流子扩散长度以及较少的表面缺陷等，近年来在太阳能电池领域受到了广泛的关注，截至目前太阳能转化效率已经达到24%。另...

Abstract： Recent years witness the resurgence of van der Waals (vdW) epitaxy where two materials of drastically different physical properties are brought together. Ample example...

Abstract： Phase transitions are both ubiquitous and fascinating.  Snow from the sky, a result of a phase transition, is run-of-the-mill in Chicago; however, we remain intri...

Abstract： Recently, antiferromagnets (AFMs) are shown to be promising candidates for next-generation spintronic materials, as they hold potential to replace ferromagnets ba...

Abstract： The efficiency, accuracy, and regulation of gene expression are offundamental importance to living systems. Single-molecule and single-cell imaging approaches have pro...

Abstract： 　　Surface wetting phenomenon is of particular importance for applications of materials, it is also a central topics in physics, biology, material science, chemistry,...

Abstract： Hybrid ferromagnetic metal/organic interface, as known as “spinterface”, can exhibit highly efficient spin-filtering properties an...

Abstract： 　　Bimetallic nanostructures of specific compositions and enclosed by certain facets can significantly alter their physical and chemical properties and thus provide t...

Abstract： 　　Quantum dots (QD) are quasi-zero dimensional structures with a unique combination of solid-state and atom-like properties. Unlike bulk or molecular materials, QD pr...

报告摘要： 原位电子显微术通过对电镜中的样品施加外场刺激使得样品结构或形貌发生变化，同时利用透射电镜来研究样品变化的机制。这一技术的发展使得对静态物质的电镜研究发展到了对物质动态...

Abstract： When atomically thin two-dimensional materials are layered, they often form incommensurate noncrystalline structures that exhibit long-period moire patterns when exami...

Biosketch： 　　Professor Qian Niu obtained a B.S. from Peking University in 1981. He went to the University of Washington for graduate studies, and received his Ph.D. in physics...

Abstract： Spin is the fundamental electronic quantum degrees of freedom in solid state materials. In superconductors, Cooper pairs, as composed of two spin-1/2 particles, can ha...

Abstract： Low power is desirable for battery-powered electronics, such as mobile phone and internet of things (IOTs) devices etc. Spintronics is considered as an emerging techno...
