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