Pressure-induced creation and annihilation of Weyl points in Td-Mo0.5 W0.5Te2 and 1T″-Mo0.5 W0.5Te2

Pressure-induced creation and annihilation of Weyl points in Td-Mo0.5 W0.5Te2 and 1T″-Mo0.5 W0.5Te2

By means of first-principles density-functional theory calculations, we investigate the role of hydrostatic pressure in the electronic structure of the Td (Pmn21) and 1T″ (Pm) phases of the Weyl semimetal Mo0.5W0.5Te2, which is a promising material for phase-change memory technology and superconduct...
