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.

新型的二维纳米材料（所谓的“ Janus”过渡金属二分法生元素（TMDS））的特征是破坏了平面外结构对称性，该结构对称能够延长激动人心的寿命，强大的旋转轨道耦合，大型的垂直抛光压力，较大的垂直压积极偏极化，以及非凡的电子机械性能。我们计划为各种“ Janus” TMD及其异质结构开发可靠，高效的合成路线，以研究其物理特性，并找到财产调整的方式。对这些材料发现的结构 - 特性关系的深入了解将为将发现的新特征转移到机电，光电和催化场的最先进技术中铺平了道路。
