제목 Role of Starting Chemical for Growth of MoS2 Monolayer and Multilayers
초록 The rise of two-dimensional (2D) material is one of the results of the successful efforts of researchers. One of the most exciting materials is MoS2. Synthesis has been always a major issue as electronic devices need reproducibility. Chemical vapor deposition (CVD) is one of the successful methods for 2D materials including graphene. Furthermore, there are various starting materials available for Mo and S source. The different source chemicals has different effects on the layers and morphology of MoS2 films. In this work, we have extensively studied the CVD technique to grow few layers of MoS2 with different starting chemicals and compare their results. We compare the results of two precursors namely MoO3 and MoCl5, show remarkable changes. The MoO3 source gives a triangular shaped MoS2 monolayer while that of MoCl5 can achieve uniform and controlled MoS2 monolayer without triangle. Eventually, we tried to explain the formation of continuous monolayer of MoS2 without any triangle on the basis of chemical reaction formalism mostly like due to one step reaction process and formation of MoS2 from gas phase to the solid phase.
