Abstract

TEMPERATURE AND FREQUENCY DEPENDENT ELECTRICAL CHARACTERIZATION OF ZNO NANOCRYSTALS

Amit Kumar Bhunia*, S. Saha and S. S. Pradhan

ABSTRACT

The present study explore the electrical properties of pressure compacted pellets of zinc oxide nanoparticles powder synthesized by simple chemical method. The HRTEM images showed the formation of nanoparticles (NPs). The room temperature absorption spectra showed a strong peak at 365 nm due to excitonic formation. The photoluminescence spectrum of ZnO NPs showed a strong emission peak at 445 nm . The electrical properties of zinc oxide (ZnO) were studied within temperature range from 250C to 400 0C and in the frequency range from 1kHz to 100 kHz for ac electrical measurements.
