Novel two-dimensional nanomaterials – so called “Janus” transition metal dichalcogenides (TMDs) - are featured by breaking out-of-plane structural symmetry that enables prolongated exciton lifetime, strong spin-orbit coupling, large vertical piezoelectric polarization, and exceptional electromechanical properties. We plan to develop reliable and efficient synthetic routes for various "Janus" TMDs and their heterostructures, to investigate their physical properties, and find the ways of property tailoring. Deep understanding of structure-property relationships uncovered for these materials will pave the way for transferring discovered new features into cutting-edge technologies in electromechanical, optoelectronic, and catalytic fields.

新型二维纳米材料-所谓的“Janus”过渡金属二硫属化物（TMD）-的特征在于打破平面外结构对称性，这使得激子寿命延长，强自旋轨道耦合，大垂直压电极化和优异的机电性能。我们计划开发各种“Janus”TMD及其异质结构的可靠和有效的合成路线，研究它们的物理性质，并找到性能剪裁的方法。深入了解这些材料的结构-性能关系，将为将发现的新功能转化为机电，光电和催化领域的尖端技术铺平道路。
