Space Charge Memory Effect in a-Si:H at low Temperatures

  • S. Heck (a1), P. Stradins (a1) and H. Fritzsche (a2)

Abstract

Space charges build up near one or both electrodes of a photoconductor unless the thermoionic current balances the photocurrent. Space charges built up also when a voltage U is applied at low T to a semiconductor containing a non-equilibrium distribution of carriers. The presence of a space charge is observed as a relaxation-current transient when the sample is illuminated at zero bias. If one type of carrier is immobile the steady state photocurrent becomes zero.
