Second harmonic generation studies on the Weyl semimetal WTe2

ORAL

Abstract

Tungsten ditelluride (WTe2) is a layered material that is both a ferroelectric and a Weyl semimetal. The coexistence of these two properties stems from inversion symmetry breaking, a condition that is sensitive to the atomic-scale lattice distortions in this material. Here, we performed second harmonic generation (SHG) studies on tungsten ditelluride. We will report on unusual and large-amplitude temperature dependent responses of the SHG as a probe of the inversion-breaking phase in WTe2.
