Recent progress of two-dimensional metallic transition metal dichalcogenides: Syntheses, physical properties, and applications

Two-dimensional (2D) metallic transition metal dichalcogenides (MTMDCs) are emerging as an appealing class of materials for a wide range research topics, including electronics, spintronics, and energy-related fields, in view their unique physical chemical properties. Notably, the controlled synthesis such promising is prerequisite. In this Perspective, we review up-to-date advances regarding syntheses properties 2D MTMDCs, well multifunctional applications. First, variety synthetic strategies exfoliation, vapor transport, atomic layer deposition, molecular beam epitaxy, systematically summarized. Second, fundamental MTMDCs introduced, charge density wave order, ferromagnetism, superconductivity. Third, versatile applications electronic devices fields discussed. Finally, challenges about exploration syntheses, interesting issues, highlighted, future directions also proposed. We believe that Perspective comprehensive insightful controllable property characterizations, application exploitations MTMDCs.
