Polyvinylcarbazole (PVK) exhibits excellent interface properties despite its structural properties playing a dominant role in nanocomposites. In the present work, we attempted to identify the interface and the molecular mechanism in pure and nano ZnO doped PVK samples. The performance of solution-cast foil samples of pure and nano ZnO sensitized PVK samples with similar (Al-Al) electrode combinations was studied by varying temperature from 30 to 170 °C. Polymer samples exhibit dielectric loss maxima around 100±10 °C. The peak is shifted towards lower temperatures, and variation is found in short circuit thermally stimulated discharge current (TSDC) study. The results show that the polymer interface and matrix behavior are suitable for microelectronic device applications. The location of the TSDC α-peak is found to be comparable with the α-peak obtained by dielectric relaxation spectroscopy. The results obtained by TSDC, XRD, and EDX analysis are in good agreement with the results of TSDC and charge transfer interface of the polymer matrix.
