Temperature- and pressure-dependent Raman scattering study of phase transitions in ZrTe$_{3}$

ORAL

Abstract

Pressure-induced superconductivity has been discovered in many classes of materials, such as the iron pnictides and transition metal chalcogenides. ZrTe$_{3}$ is a representative member of the latter whose ground state can be tuned between charge density wave and superconducting phases via pressure or intercalation. Microscopic information about the structural evolution of ZrTe$_{3}$ in response to applied pressure is lacking at present. In this talk, we describe a temperature- and pressure-dependent Raman scattering study of the structural evolution of ZrTe$_{3}$ through its temperature- and pressure-dependent phase transitions.
