•We demonstrate the collective CDW motion in the 2D compounds.•We present evidence of the unidirectional CDW in the TbTe3 and GdTe3.•We determined the parameters of the threshold electric field for the CDW sliding.
Nonlinear transport properties in the layered TbTe3 and GdTe3 rare-earth tritellurides with a charge-density-wave (CDW) transition above room temperature have been studied along different crystallographic orientations. The pronounced effect of collective CDW motion is observed along c-axis and is absent completely in the perpendicular direction demonstrating the unidirectional character of the CDW. In contrast to one-dimensional CDWs the threshold electric field for CDW sliding is linearly temperature dependent in a wide range of temperature.
