About Tungsten Telluride WTe2 Powder:
Tungsten telluride (WTe2) is a transitional metal chalcogenide with a layered structure. In its orthogonal cell, the tungsten chain presents a one-dimensional distribution along the A axis of the tellurium layer. It is a kind of non-magnetic semi-metallic material.
Tungsten telluride (WTe2) is an inorganic semimetallic compound. Tungsten ditelluride is found to have very large magnetoresistance: at a magnetic field of 0.5 Kelvin, 60 teslas, the resistance increases by 13 million %. The resistance is proportional to the square of the magnetic field, showing unsaturation. This may be because the material is the first example of a compensating semi-metal where the number of movable holes is equal to the number of electrons tungsten ditelluride has a layered structure similar to many other transition metal halogen compounds, but its layered structure is distorted, and many of them share a honeycombed lattice that is difficult to identify in WTe2. Instead, tungsten atoms form zigzag chains that are thought to behave as one-dimensional conductors. Unlike electrons in other two-dimensional semiconductors, electrons in WTe2 can easily move between layers
The magnetoresistance effect in WTe2 decreases under pressure. When the pressure exceeds 10.5 GPa, the magnetoresistance disappears and the material becomes a superconductor. At 13.0 GPa, the superconducting transition occurs below 6.5 K.
Two – and three-layer thick WTe2 have also been observed to be polar metals, and the theory of electrical polarization with metallic behavior and conversion suggests that polarization is caused by vertical charge transfer between layers, which in turn is caused by interlayer sliding.
