Abstract
Thermally stimulated discharge ( TSD) currents excited at 110°C by 117 V in 20 μm thick polystyrene (PS) films in contact with Al, Zn, Pb, Cd, Cu and Ni have been measured keeping the other electrode as Al. TSC parameters are observed to change with the choice of electrode material. Maximum charge is stored by PS films in contact with Cu. The observed polarization is explained in terms of detrapping of charges injected from the electrodes with subsequent space-charge formation. The dependence of dark current at 50°C in metal-PS-Al systems on applied voltage in the range 3–117 V has also been investigated. Current density-square root voltage plots are observed to have straight portions at high field values. Zero field current density extrapolated from these plots and TSC activation energy are found to vary with metal work function qualitatively in a similar manner.
