Abstract
The physical background of the method of temperature-modulated steady-state space-charge-limited currents is described. It is a self-consistent spectroscopic method applicable to the determination of both arbitrary energy distributions of bulk electron-localised states and charge carrier mobility. It is based on the measurement of the current-voltage characteristics together with the current activation energy-voltage dependence in the space charge regime, i.e. the current and its change due to the modulation of temperature are measured at a given applied voltage. The applicability of the method is illustrated by means of computer-simulated characteristics, calculated for various typical distributions of traps.Keywords
