dc surface conductance as a tool for the study of the space charge layer of thin film semiconductor electrodes

The space charge layer of chemically deposited CdS film electrodes in different electrolytes was studied by dc surface conductance measurements. The results obtained by this method are compared with those derived from capacitance and modulated transmittance. The values of the flat band potential obt...
