Simulation of transient curret through polymethylmathacrylate thin films based on a charge density wave model

Abstract

A piecewise continuous, time dependent di®usive coupling in a classical onedimensional randomly pinned charge density wave model has been used for the analysisof experimentally observed transient current data for polymethylmethacrylate thin films. Satisfactory agreement has confirmed that this can be a dynamical model forthe behavior of the transient current. The analysis also suggests the presence of three different regimes in the decay of the transient current.
