The rapid development of two-dimensional (2D) materials has led to tremendous interest in the study of graphene and a series of mono- and few-layered transition metal dichalcogenides (TMDCs). One major attraction of TMDCs is their semiconducting nature with indirect to direct bandgap transition, when thinned from bulk to few- and mono- layers. Molybdenum disulfide (MoS2) is one of the 2D TMDCs that has gained increasing attention due to its promising optical, electronic, and optoelectronic properties. In this thesis, I will discuss my research on the synthesis of 2D MoS2 and the characterization of its optical properties by Raman, Photoluminescence (PL) and UV-Vis spectroscopy. Next, the application of 2D TMDCs for FETs and solar cells will be reviewed. Finally, my extended work on the oxide form (transition metal oxides) and zero-dimensional (0D) form of TMDCs will be discussed. Efficient solar cells constructed by MoO3 and other oxides, and the future application of 0D TMDCs will also be evaluated.
