The Landauer-Büttiker Formula and Resonant Quantum Transport

The Landauer formula—named after Rolf Landauer, who first suggested its prototype in 1957 —is a formula relating the electrical resistance of a quantum conductor to the scattering properties of the conductor. In the simplest case where the system only has two terminals, and the scattering matrix of the conductor does not depend on energy, the formula reads where is the electrical conductance, is the conductance quantum, are the transmission eigenvalues of … Tīmeklis2.3.1 Landauer Formula.
