Currently this is the book providing a thorough introduction and a
unified theoretical basis for the interpretation of equilibrium
transport processes in amorphous hydrogenated tetrahydrally coordinated
semiconductors - a topic of great interest to physicists and material
scientists (first devices for practical applications are already being
manufactured). Most of the relevant literature is reviewed with
particular emphasis on the approach developed by the authors. It
explains most of the experimental data and allows the extraction of
information about microscopic transport processes and parameters from
equilibrium transport data. This work treats electronic transport in the
mentioned type of semiconductors and in particular in a-Si: H and a-Ge:
H. From elementary concepts the theory is developed towards higher
degrees of completeness and sophistication. Further refinements for
coping with the complexity of real systems are given. The comparison of
theory with experiment is an important part of the boo
