Relations Between Impedance Data and Local Properties

1 Relations Between Impedance Data and Local Properties 

The quantitative analysis of conventionally obtained grain boundary impedance data is problematic if grain boundary properties strongly vary from boundary to bound- 

values as in a quasi one-dimensional case (electrodes on two sides, Fig. 14b) 

Similar considerations are valid with respect to the grain boundary capacitance. Again, a correction factor hc takes account of displacement currents across neighboring grain boundaries and
