Tungsten Telluride Sputtering Targets (WTe2)

Tungsten(IV) telluride (WTe2) is an inorganic semi-metallic chemical compound. The resistance is proportional to the square of the magnetic field. This may be due to the material being the first example of a compensated semimetal, in which the number of portable holes are the same as the number of electrons. The tungsten ditelluride structure is layered, and the substance can be exfoliated into thin sheets down to monolayers. However, electrons can quickly move between the layers, unlike in other two-dimensional semiconductors. The fraction of charge carriers is 0.005 per formula unit (WTe2).
