Dielectric and Electrical Behaviour of Zno and Cdo Semiconducting Materials With and Without Mn Doping

Abstract

ZnO and CdO pellets with and without Mn doping were prepared by using Hydraulic pressure machine at room temperature. The effect of Mn content (1,3,5 wt % ) on the electrical properties have been carried out by Keithley meter. The result shows that the resistivity decreases as increasing Mn content. Impedance analyzer are used for dielectric behavior and results shows that decrement of dielectric constant as well as dielectric loss with the increment of frequency.
