Current density time reversal relations

Peculiarities of a response to potentiodynamic perturbation are determined in a more simple way when the charge transfer process is reversible and Eq. (3.49) applies. However, before starting the analysis of such processes, several notes should be made. First of all, it should be noted that concentrations [M"" ] and coincide in the system that contain no ligand. In this case, the surface concentration of is the only parameter relating dependencies of overvoltage 1 of the current density i on time. According to [14], when tj = vt, equation ... 

Applying the time-reversal operator to the current densities, we derive the relations... 

The noise spectral density is l/f type in the frequency band 10 mHz to 300 Hz in normal and reverse operation mode. Noise spectral density is a quadratic function of the current, when the electric field strength in isolating layer is so low that avalanche process caimot occur. Measurement performed at very low frequency band 10 mHz to 1 Hz reveals that for some samples noise is l/f type, but it was observed some time instability, which is probably related to the self-healing process.
