Part 1 Band structure of semiconductors: the crystal Hamiltonian adiabatic approximation phonons the one-electron approximation Bloch functions nearly-free-electron model energy gaps spin-orbit coupling and orbital characteristics band structures chemical trends k.p perturbation and effective mass temperature dependence of energy gaps deformation potentials alloys. Part 2 Energy levels: the effective-mass approximation electron dynamics Zener-Bloch oscillations Landau levels plasma oscillations excitons hydrogenic impurities hydrogen molecule centres core effects deep-level impurities scattering states impurity bands. Part 3 Lattice scattering: general features energy and momentum conservation acoustic phonon scattering optical phonon scattering polar optical mode scattering piezoelectric scattering scattering-induced electron mass mobilities appendix - acoustic waves in the diamond lattice. Part 4 Impurity scattering: general features charged-impurity scattering neutral-impurity scattering central-cell contribution to charged-impurity scattering dipole scattering electron-hole scattering electron-electron scattering mobilities appendix - Debye screening length, average separation of impurities, alloy scattering. Part 5 Radiative transitions: transition rate photo-ionization and radiative capture cross-section wavefunctions direct interband transitions photo-deionization of a hydrogenic acceptor photo-ionization of a hydrogenic donor photo-ionization of quantum-defect impurities photo-ionization of deep-level impurities summary of photo-ionization cross-sections indirect transitions indirect interband transitions free-carrier absorption free-carrier scattering of light appendix - justification of effective-mass approximation in light scattering. Part 6 Non-radiative processes: electron-lattice coupling the configuration-co-ordinate diagram semi-classical thermal generation rate thermal broadening of radiative transitions thermal generation and capture rates electron-lattice coupling strengths selection rules for phonon-impurity coupling phonon-cascade capture the Auger effect impact ionization appendix - the multiphonon matrix element.
