Tungsten ditelluride (WTe2) is a transition metal dichalcogenide with numerous advantageous properties and characteristics, which makes it an ideal material for a wide range of electronic applications. Past studies have established that 2D WTe2 crystals arranged in a single layer form the first monolayer topological insulator, exhibiting topological properties that survive up to very high temperatures (~100 K).
