Low-dimensional nanomaterials have attracted widespread attention in various fields of research endeavors owing to their unique and desirable physical properties. We have synthesized various kinds of high-quality low-dimensional materials using bottom-up (chemical vapor deposition, ligand exchange approach, solution phase deposition, and hydrothermal reaction) or top-down method (mechanical and liquid phase exfoliations). Furthermore, we modulated the physical and optical properties of low-dimensional materials through heterostructure formation, phase transition, vacancy formation, functionalization, and chemical composition control, and demonstrated several applications of property-modulated low-dimensional nanomaterials including ultrasensitive chemical sensor and electrochemical water splitting with outstanding stability and performance. We also investigated promising possibility of low-dimensional nanomaterials in various components of photovoltaics including transparent conducting electrode, charge transporting layer, and interfacial buffer layer. The low-dimensional nanomaterials enhanced the performance and flexibility of functional devices through the enhanced charge transfer efficiency, mechanical robustness, and light absorption capability.
