Abstract

In this investigation, we explore the synthesis of MoS2 through thermal evaporative deposition, seeking to uncover the growth dynamics and structural evolution of MoS2 under varied experimental conditions. By adjusting the temperature and the carrier gas, this study targets the fabrication of vertical multilayer MoS2 and its growth mode. Our analysis demonstrates that thermal conditions markedly influence flake morphology and dimensions, leading to a notable shift from AA to AB stacking configurations as temperatures rise in the vacuum. Additionally, the application of carrier distinctly modifies growth behaviors, enhancing the uniformity of nucleation sites and the propensity for lateral flake expansion. The insights gained from this research highlight the adaptability and effectiveness of thermal evaporative deposition in producing MoS2, thereby enriching our understanding of the fundamental mechanisms guiding MoS2 synthesis.
