Abstract
The energy-loss method has been applied for more than ten years to a large variety of transport problems. The surprising success apparently is due to the simplicity of the concept as well as of the mathematical treatment. In addition to a previous review (by Gerlach and Grosse) where a number of formulae for basic applications were derived and compared with experiments, the author gives a general intuitive and analytic introduction into the method and the general structure of the results. Furthermore, he describes recent fields of application. Most important are scattering of impurities by clusters, by ions near surfaces, and by dislocations and precipitations. A new interesting feature is a localisation of carriers appearing in low-conduction systems. A most recent application of the energy-loss method concerns drifting carrier systems and transport in external magnetic fields. Finally he discusses the relation of the energy loss to a force balance and report results on electron-electron scattering and the effect of polar optical phonons on transport coefficients.
