A study of absorption currents in acrylic acid-doped polystyrene

Abstract

The absorption currents in the discharge mode of acrylic-acid (AA)-doped solution-grown polystyrene (PS) films, prepolarized at 358 K with different fields, have been analyzed in the temperature range 313-358 K. Space charge due to trapping of injected charge carriers in energetically distributed traps is considered to account for the observed currents. Two relaxation peaks centered at 328 K and approximately at 348 K, respectively have been observed in isochronal current thermograms.<>
