In this paper, an approximate analytical method for calculating the surface impedance of superconducting thin film is presented. This method is based on Maxwell's equations, vector identities, Stoke's theorem, Gauss's theorem, differential operations in various coordinates and Poynting's theorem analysis for an approximate model of the current ...

Journal of The Electrochemical Society, 1983
Capacitance‐voltage (C‐V) measurements were made for the single crystal semiconductors ; , , p‐Si,, , and in acetonitrile containing a number of redox couples whose potentials spanned a potential regime much wider than the bandgaps. The flatband potential evaluated from capacitance‐potential (C‐V) measurements (Mott‐Schottky plots) exhibited three ...
