Abstract
Free holes generated on the illuminated surface of an iodine crystal are injected into its bulk by applied voltage pulses. The space-charge-limited currents obtained with sequential pulses at various voltages and with different time intervals between the pulses allow one to calculate the density of trapped charge and the characteristic time constants of trapping and release. It is also possible to estimate the concentration of trapping levels, their capture cross section, and their energy position in the forbidden gap, in good agreement with previous results.Keywords
