Abstract
Dynamic resistance, noise spectrum and electron diffraction studies on
electron irradiated orthorhombic TaS3 were performed in the temperature
range of 75 K-280 K. At low defect concentrations (< 10-4
displacement per Ta atoms) the threshold field of the nonlinear
conductivity (ET) increases linearly with the irradiation dose in spite
of the fact that there is hardly any effect on the Peierls transition
temperature, Tp = 221 K. Concomitantly the sharp peaks in the noise
spectrum are smeared out and the broad band noise level increases. At
higher defect concentrations, Tp decreases and the transverse coherence
of CDWs is lost. In this regime the sharp threshold disappears from the
nonlinear characteristics.
