Single-crystal electrolytes impedance

Typical values of o and a, as well as the faradaic resistance Rf, series resistance Rs (and the film resistivity p calculated thereby, assuming that the electrolyte resistance can be neglected) are presented in Table 3 for polycrystalline and single-crystal diamond electrodes and a DLC electrode [69-77]. By comparing the impedance... 

Doping densities in single-crystal semiconductor samples can usually be determined from capacitance and voltage measurements uing suitable electrolyte contacts. However, in the case thin polycrystalline layers fabricated for PV devices, dark currents arising from cracks and pinholes often make interpretation of impedance data difficult In this case a different approach based on analysis of the EQE response may be useful. If the minority diffusion length in the sample is sufficiently small to fulfill the condition aL 1-as is usually the case for...
