报告摘要： 　　WTe2因其强自旋轨道耦合、半金属输运、迥异的对称性、二维受限和高迁移率等特性，成为一种物理内容十分丰富的新型量子材料。我们就此材料开展了三项工作：1）利用迁移率谱的方....

报告摘要： Water splitting continues to attract much attention for the purpose of producing hydrogen, which is regarded as the most promising altern...

报告摘要： We study the strong coupling between photons and atoms that can be achieved in an optical nanofiber geometry when the interaction is dispersive. While the Purcell enha...

Abstract: 　　Topological insulators (TIs) are characterized by an unusual electronic structure exhibiting both insulating bulk and robust metallic surface states (SSs). This uni...

Abstract： 　　Electrochemical reactions, e.g. oxygen reduction (ORR), hydrogen evolution (HER) and oxygen evolution reaction (OER), are key to energy conversion and storage. For...

报告摘要： 1929年德国数学家和物理学家外尔在狄拉克方程的基础上预言一种无质量的具有相反“手性”的粒子，被称为外尔费米子，但因为其违反“左右”对称性（即宇称守恒）而未被广泛接受。1957年杨....

Abstract： Synthesis of interfaced nanoparticle dimers made of asymmetric compositions (i.e., interfaced heterodimers) is challenging because it is difficult to manipulate the na...

Abstract： Electron microscopy is a very standard powerful technique for the study of atomic structure of materials. In this talk, I will discuss two recent developments in t...

报告摘要： The boom of graphene research has stimulated great interest in two-dimensional form by other elements, either single element or composite materials. Among these 2D mat...

Abstract: 　　The past few years witnessed the explosion of research on photovoltaic cells based on the hybrid lead halide perovskites, in particular CH3NH3PbI3. Within a short pe...

Abstract: 　　Bacteria living in confined geometries are commonly found in clinical and natural environments. We are particularly interested in the behavior of bacteria conf...

Abstract: 　　Ultrathin films of transition metal dichalcogenides (TMDs) are of great current research interests for their promises in two-dimensional electronics, optoelectronics...

Abstract： Atomistic structures of materials occupy a central position, when establishing a correspondence between materials performance and chemical compositions. Theoretical pr...

报告摘要：　　氧八面体扭转是钙钛矿薄膜(ABO3)中一种常见的晶格畸变方式。氧八面体扭转直接决定B-O-B键角和键长，所以其对研究薄膜的电学和磁学性质有非常重要的意义。由于氧原子的电子数很少....
