Landauer-buttiker
The Landauer-Büttiker (LB) method (also known as the scattering method) establishes the relation between the wave functions (scattering amplitudes) of electrons in a quantum junction and the conducting properties of this junction.The LB method can be applied to find the current … Skatīt vairāk The main idea of the scattering approach to the conductance was first formulated by Rolf Landauer [1, 2]. He proposed, that the conductance of … Skatīt vairāk Now we are ready to see in detail, how the transmission coefficient can be used to calculate the current through a quantum junction, in particular we will derive the Landauer … Skatīt vairāk Consider now the single-channel case with the imperfect transmission T\ne 1, repeating the same calculation as in (2.85) we obtain This is … Skatīt vairāk Perfect Wire Consider now the conductance of a perfect wire adiabatically coupled to two electrodes. “Perfect wire” means that there are several open reflectionless channels with transmission coefficient … Skatīt vairāk Tīmeklis突然想到，根据Landauer-Buttiker公式，对于一个contact，一个电子的电导具有上限量子电导G0，以及相应的…
