Cross sections for electron interactions in condensed matter

The fundamental components of Monte Carlo algorithms for the simulation of electron transport in matter are the differential and total cross sections for the relevant interaction mechanisms. We present different theoretical models And approximations to compute these cross sections for elastic scattering, inelastic collisions and bremsstrahlung emission of electrons with kinetic energies larger than about 100 eV. We limit our considerations to. those models that are broadly applicable and suited for efficient random sampling. The approximations underlying the various models and their range of applicability are discussed. Copyright (C) 2005 John Wiley & Sons, Ltd.
