Evidence for realignment of the charge density wave state in ErTe${}_3$ and TmTe${}_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

Abstract

We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te${}_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress. Measurements of the elastocaloric effect, resistivity, and elastoresistivity allow us to demonstrate the importance of in-plane antisymmetric strain on the CDW and to establish a phase diagram. We show that modest tensile stress parallel to the in-plane $a$-axis can reversibly switch the direction of the ordering wavevector between the two in-plane directions. This work establishes $R$Te${}_3$ as a promising model system for the study of strain-CDW interactions in a quasi-2D square lattice.
