Popis: A general method for processing deep level transient spectroscopy (DLTS) data is presented. It is shown that the theoretical model is a two‐dimensional Fredholm equation of the first kind with a four‐dimensional integral kernel. The method is based on the numerical solving of the inverse ill‐posed problem of the theoretical model via regularization algorithms. Starting from a two‐dimensional C(T,t) surface one can obtain the corresponding C0(E,σ) surface, i.e., the continuous distribution equivalent to the deep levels concentrations for a given sample in both energy and cross‐section coordinates.
