Observation of the Poole-Frenkel effect in Tantalum Polymer capacitors

I-V and I-time measurements to characterize the Polymer-Dielectric interface of Tantalum/Ta 2 O 5 /Polymer capacitors were performed. The interface consists of a conducting polymer - PEDOT (poly 3,4-ethylenedioxythiophene) and Ta 2 O 5 . The leakage current measurements on these capacitors were foun...

Summary:I-V and I-time measurements to characterize the Polymer-Dielectric interface of Tantalum/Ta 2 O 5 /Polymer capacitors were performed. The interface consists of a conducting polymer - PEDOT (poly 3,4-ethylenedioxythiophene) and Ta 2 O 5 . The leakage current measurements on these capacitors were found to be consistent with Poole-Frenkel Emission in the bulk of the dielectric.
