Temperature dependence of the excitation spectrum in the charge-density-wave ErTe${}_3$ and HoTe${}_3$ systems

F. Pfuner, P. Lerch, J. -H. Chu +3

We provide optical reflectivity data collected over a broad spectral range and as a function of temperature on the ErTe${}_3$ and HoTe${}_3$ materials, which undergo two consecutive ch…
