In this chapter the Landauer-Büttiker method (also known as the scattering method) for coherent transport is considered. This method establishes the relation between the wave functions (scattering amplitudes) of electrons in a quantum junction and the conducting properties of this junction. The basic quantum junction model and results from the quantum scattering theory are discussed. The Landauer formula in the single channel case and the general multi-channel and multi-terminal formalism are discussed.
