P \approx exp(-E_0/E)  \end{equation}  The probability comes in the right hand side of equation (5), reducing the force felt by CDW by a fraction of P. The weak electric field, i.e. $E_0 >> E$ leads to vanishing of the force.In other words, the electric field is not sufficient to "depin" CDW.  Thus the conductance is negligible. For large field $E >> E_0$, the force is nonlinearly dependent upon E, thus the second term in equation (4) shows up. Moreover, $E_0$ depends upon the gap energy; therefore, the relationship between the lattice spacing and the threshold electric field will also be investigated. Secondly, this project willalso  investigate the relationship between the AC  conductance dependence on and the  frequencyFor weak AC electric field, CDW remains pinned regardless  of applied field. This problem was dealt with by considering  the frequency. classical single particle model. For
