Study of dielectric properties of nanophase silver iodide

  • M Abdulkhadar
  • Binny Thomas


Dielectric properties of nanophase AgI are studied over the frequency range from 100 kHz to 3 MHz at different temperatures. The values ofε, tanδ andσ ac are considerably larger than those reported for crystalline pellets of AgI, but they show a similar trend in variation with frequency and temperature. The increase in these values are attributed to the defect structure of the nano-particles.
