Sliding charge-density-wave in two-dimensional rare-earth tellurides
Abstract
Nonlinear transport properties are reported in the layered DyTe3 compound at temperature below the charge-density-wave (CDW) transition, TP=302 K. Conductivity is increasing sharply above the threshold electric field. Under application of a rf field Shapiro steps are clearly observed. These features demonstrate for the first time CDW sliding in two-dimensional compounds.
