Very long current transients in reverse-biased almost ideal n/sup +/-p junctions

The current transients due to a change in reverse-bias voltage in almost ideal n/sup +/-p junctions obtained by proper gettering processes are discussed. Very long relaxation phenomena are observed. The transient current is fitted by a t/sup -v/ law with v approximately=0.7 and by an exponential with a relaxation time of 45 min. The transient current amplitude is virtually proportional to the volume of the depletion region swept by changing the reverse bias.<
