Trap spectroscopy by the fractional glow technique

A theory of the fractional glow technique (FGT) for an arbitrary heating regime and first-order recombination kinetics is developed. In order to describe a trap distribution function (TDF) its characteristics: (i) the mean activation energy, (ii) the mean frequency factor, (iii) the recombination intensity, (iv) the FGT energy spectrum as the TDF image in activation energy scale, and (v) the FGT frequency factor spectrum as the TDF image in frequency factor scale are presented. Relations are obtained which permit direct calculation of these characteristics without a computer simulation of the fractional heating regime. Regularities of the FGT energy spectrum formation as well as the errors of the mean frequency factor estimate for various TDF's are discussed.
