Abstract
Abstract The charging current of the space charge layer of a CdS(0001)/aq. KCl junction was measured by Time Domain Spectroscopy in the short time region. The relaxation spectrum consists of a multitude of exponentials, which is interpreted by a heterogeneous semiconductor surface. This explains the dependence of conventional Mott Schottky plots on frequency and resulting errors in the determination of flatband potential and donor density.
