The complex impedance diagrams of the samples all contain three recessed semicircles, which correspond to the grain response, the grain boundary response, and the polarization response of the electrode from high frequency to low frequency.
The complex impedance graph of the sample consists of three recessed semi-circles corresponding to the grain response, the wafer boundary response, and the polarization response of the electrode from high to low frequencies
The complex impedance diagrams of the samples all contain three concave semicircles corresponding to grain response, grain boundary response and electrode polarization response from high frequency to low frequency<br>
