Applications

Two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted increasing attention owing to their diverse properties ranging from insulator to metal and promising for a wide range of applications. TMDs and their 2D van der Waals heterostructures have been proposed and demonstrated in various applications, such as electronics, optoelectronics, photonics and photovoltaics.

As a member of 2D TMDs materials, tantalum disulfide (TaS₂) has attracted increasing attention owing to its initial peculiar metallicity. The potential applications include as a conductive and active catalyst in the hydrogen revolution reaction and as a buffer layer for organic photovoltaics.
