Abstract

The quantum tunneling model of depinning of charge-density waves in linear chain conductors can be simplified and made more concrete by reviving a soliton model similar to that studied in 1978 by Maki and by Larkin and Lee. They rejected a model of solitons on individual chains pinned by impurity fluctuations because the energy involved is far less than 1°K. However the transverse coherence distance includes 105 or 106 parallel chains. There is only one thermal degree of freedom for motion parallel to the chains in a domain of this area and a length containing a pinned soliton or phase kink. What is pinned is a parallel array of such phase kinks of average spacing Ld. The current acceleration, dJ/dt, from a field, E, by tunneling, is analogous to Josephson current flow across a tunnel junction from a phase difference.
