The Wigner function approach to electron transport in semiconductors is commonly used to describe the properties of electronic devices. Until now, this approach was restricted to the description of the conduction band electrons, under the effective-mass approximation. A multi-band, non-parabolic transport model has been introduced; numerical results for multi-band transport have been obtained until now only for very elementary examples and more extensive numerical work is underway; numerical results for non-parabolic, single-band transport have been more numerous and easier to obtain, so this aspect has been studied in more detail. We shall illustrate some of the results in this symposium.
