Can we estimate the density of localized gap states Their presence is noticed in measurements for instance of drift mobility, photoconduction, (Arnoldussen, Bube, Fagen and Holmberg (1972a, b)Weiser(1972)), thermo-stimulated currents (Kolomiets and Mazets (1970)), recombination radiation (Kolomiets, Mamontova, and Babaev (1970)), and high field conduction. A density of gap states cannot be obtained from these experiments though, without having values for the appropriate trapping and recombination cross sections.

For example, the most commonly used thermal method is and will almost certainly continue to be differential scanning calorimetry (DSC), hence here we have dedicated three chapters to the technique covering the principles, the optimal use of the method, and pharmaceutical applications. We then include chapters on thermo-gravimetric analysis, modulated temperature DSC, microcalorimetry, high sensitivity DSC, thermal microscopy, thermally stimulated current, and dynamic mechanical analysis, all of which have attracted great interest within the pharmaceutical field. In all cases, these chapters combine elements of theoretical background, measurement optimization, and pharmaceutical applications. It is our profound hope that in this way we will achieve a suitable mixture of depth, relevance, and accessibility.
