Revealing the nature of the charge density wave order of ErTe${}_3$ via Raman scattering under anisotropic strain

Theotime Freitas, Mattia Udina, Alexandr Alekhin +7

The nature of the charge density wave (CDW) order of the rare-earth tritelluride ErTe3 is investigated by Raman scattering under anisotropic strain. The CDW state of ErTe3 is uncon…
