44: 35: 219: 146: 493:: 13 million percent resistance increase in a magnetic field of 60 tesla at 0.5 kelvin. The resistance is proportional to the square of the magnetic field and shows no saturation. This may be due to the material being the first example of a compensated semimetal, in which the number of mobile holes is the same as the number of electrons. Tungsten ditelluride has layered structure, similar to many other 434: 1001:

Subsequent studies using other techniques have been consistent with the transport results, including those using 587:, simultaneously hosting metallic behavior and switchable electric polarization. The polarization was theorized to originate from vertical charge transfer between the layers, which is switched by interlayer sliding. 1482:
