ABSTRACT:
The exceptional properties of two-dimensional atomic crystal materials can be attributed to their distinctive structural characteristics. Compared to graphene, Two-Dimensional Transition Metal Dichalcogenides (2D-TMDs) exhibit diverse sizes and adjustable band gaps, making them appropriate for utilization in the field of microelectronics. The field of optoelectronic devices displays significant potential for utilization across diverse domains. This article comprehensively analyses the methodologies employed in manufacturing 2D-TMDs materials, specifically «top-down" and "bottom-up" techniques. The research additionally provides a comparative evaluation of frequently utilized techniques. Furthermore, a synopsis of their advantages and disadvantages is presented. Concurrently, tackling the practical obstacles linked to the chemical vapor deposition methodology concerning forthcoming wafer-level 2D- TMDs devices is crucial.
Keywords: 2D-TMDs, top-down approach, Bottom-up growth model, Exfoliation, chemical/Physical vapor deposition PVD/CVD.
