Thermally stimulated discharge in CDW systems

We have investigated dynamics of various CDW compounds in the low temperature insulating highly polarisable state by means of thermally stimulated discharging. Current spectra are observed in the temperature range where the response time of the CDW exceeds seconds. Special attention is given to the o-TaS_3 that shows the most complex behavior.
