By fitting theexperimental data to space-charge limited conduction, bulk-limited Poole–Frenkel emission andthermo-ionic emission theory, it was observed that these models can not be applied to evaluatejunction parameters for the investigated SB diode. Preliminary resultsindicated that the charge transport proceedsby different mechanism for low and high values of the applied voltage under forward and reverse bias conditions. Itwas found that the charge transport is governed by hopping processes for lowvalues of the forward bias. However, for higher values of the forward bias, thecharge transport controlled by the bulk limited procesess. The same voltagedependence was also observed for reverse bias conditions.
