Impedance spectroscopy is used to study the frequency dependent electrical parameters such as impedance, dielectric constant and conductivity of ZnO nanorods MSM structure in the range of 1 Hz to 10MHz under atmospheric conditions. The real part of impedance (Z’) showed two semicircles that corresponds to the distribution of the grain boundries and electrode process. SEM image shoewed the densily packed ZnO nanorods on the surface of silicon substarte whereas, XRD revealed the grown nanorods have c-axis oreintation.The results shows that the impedance, dielectric increases as the frquency decreases while the conductivity showed the opposite behavior.
