摘要:

石墨烯的發現掀起了人們對二維晶體材料的探索熱潮。單層或少數層過渡金屬硫族化合物（TMDs）是二維晶體材料的典型代表，此類材料的帶隙合適、電子遷移率和熱導率高、光吸收強、比表面積大，在新型光電器件、光/電催化、鋰離子電池電極、氣體傳感及生物醫學等領域蘊藏著巨大的應用潛能。特別是，對于TMDs二維晶體與其他材料復合而成的納米結構，強烈的界面耦合作用對材料物理和化學特性的調控至關重要，甚至可能導致新奇特性，預示著新功能和新應用。本論文詳細綜述了TMDs二維晶體基復合材料的制備方法、結構與性能的界面調控及其潛在應用，并指出了該研究領域仍存在的問題及未來發展方向。

Abstract:

The discovery of graphene promotes the exploration of two-dimensional (2D) materials. Single-layer or few-layer transition metal dichalcogenides (TMDs) are the representative ones, and they exhibit enormous potential applications in many high-tech fields, such as, electronic devices, photo/electro-catalysis, batteries, sensors, and so on, owing to adjustable band gap, high electron mobility and thermal conductivity, strong light absorption and large specific surface area. Especially, as for the TMDs-based 2D composites, the strong interfacial coupling is crucial to optimize their physical and chemical properties, which even induces novel properties and generates new functions for practical applications. The fabrication methods, interfacial coupling effects and applications are systematically summarized and discussed. Accordingly, the challenges and opportunities in this promising research area are also presented.
