Drastic pressure effect on the extremely large magnetoresistance in WTe2: Quantum oscillation study. PRL 115, 057202 (2015)

       We present the quantum oscillation study of the magnetoresistance for WTe2 single crystals under ambient and high pressure. By analyzing the Shubnikov-de Haas oscillations of magnetoresistance at low temperature, four Fermi surfaces are revealed. A drastic suppression of the extremely large magnetoresistance(XMR) with increasing pressure is observed, which is accompanied by a change of the Fermi surface topology. The correlation between them provides support for the mechanism that the XMR of WTe2 originates from the electron hole compensation.
