Problem formulating. The authors of the work have previously found that in rare-earth tritellurides, upon cooling the sample and its subsequent isothermal exposure at a temperature T0 below the Peierls transition, the pinning of the charge density wave (CDW) increases, which is probably due to the appearance of a nonequilibrium CDW state and its relaxation to the equilibrium state.

Goal. To study the effect of the evolution of the non-equilibrium state of the charge density wave in the compounds RTe3, (R: Tb, Ho, Tm, …) by means of low-temperature electrical measurements.

Result. The time dependences of the process of relaxation of a nonequilibrium state at different temperatures, in the regimes of a stationary and moving CDW, are determined, and the possibilities of transition and stabilization of the system in the intermediate state are also found.

Practical meaning. The prospect of using layered quasi-two-dimensional compounds as the element base of modern electronic devices and devices.
