An investigation on Transient Current characterstics in polymeric double layer Thin Films

Pooja Saxena, Prashant Shukla, M.S. Gaur


Transient current characteristics in charging and discharging modes for PVDF-PMMA double layer polymer samples replicated various mechanisms responsible for the transient conduction phenomenon. The isochronal are characterized by well-defined peaks, indicating thermal activation of discharging current over a particular temperature range. The time-dependent charging current characteristics in double-layered samples suggested space charge limited conduction (SCLC) mechanism and also that the polarization may be due to dipolar orientation and trapping of charge carries in the bulk.
