Raman signatures of inversion symmetry breaking and structural phase transition in type-II Weyl semimetal MoTe2

, 2016
Transition metal dichalcogenide MoTe$_2$ is an important candidate for realizing the newly predicted type-IIWeyl fermions, for which the breaking of the inversion symmetry is a prerequisite. Here we present direct spectroscopic evidence for the inversion
