where $\Gamma$ is the damping coefficient determined by experiment and m is the collective mass of CDW. By changing parameters in equation (5), one can obtain the "diode-like" conductance of depinned CDW.
The approach of dealing with DC electric field is to consider the scattering and tunneling of CDW when interacting with distorted lattice potentials. It is clear that the larger the applied field, the more possible CDW will tunnel through the periodic potential, which is the analogy of Zener diode \cite{Zener_1934}.
