Pulsed RadiationInduced Conductivity of Polymers in Strong Electric Fields

Russian Journal of Physical Chemistry B. 2015. Vol. 9. No. 4. P. 648-657.

Abstract—A theoretical analysis of the nonlinear field dependence of the pulsed radiationinduced conductiv ity of polystyrene in strong electric fields is performed. An explanation of the previously uncomprehended phe nomenon of the sharp increase in the radiationinduced electrical conductivity in the presence of an electric field with a strength of above 5 × 107 V/m is proposed. This behavior cannot be explained within the framework of Onsager’s theory of the fieldassisted thermal production of free charges from generated geminate pairs.
