A generalized Landauer-Datta-Lundstrom electron transport model

General problems of electronic conductivity, reasons for a current flow, the role of electrochemical potentials, Fermi functions, the Fermi window for conduction, the elastic resistor model, different electron transport regimes, conduction modes, and transmission coefficients are discussed in terms of the “bottom-up” approach to nanoelectronics. The generalized model of electron transport in the linear response regime developed by R. Landauer, S. Datta, and M. Lundstrom, which can be applied to conductors of any size, scale, and arbitrary dispersion in the ballistic, quasi-ballistic, or diffusive regimes is described.
