WORLD SCIENTIFIC PUBL CO PTE LTD Location. … 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

Tīmeklisare behind the formulae used in [21] for studying specific properties of such systems. Now let us describe the strategy followed to achieve the results. TīmeklisI would like to plot conductance G ( E) versus energy E, with E m i n = − 1 e V, E m a x = 1.5 e V, using the Landauer-Buttiker approach: G ( E) = ∫ − π / 2 π / 2 T ( E, θ) cos θ …
Tīmeklis2011. gada 1. aug. · is given by Landauer Buttiker formalism as: G c = (N. e 2 /h) T, where N is the number of conduction channels in parallel, T is transmissi on coefficient, and h is Plank constant, 6.625 10 -34 J.s. Tīmeklis2014. gada 12. jūn. · According to the Landauer–Buttiker formula (equation ), the transmission coefficient is a quantity characterizing the transport of electrons. In figure 9, we present the results for this quantity obtained by invoking the program 'CheckTransmission'.

TīmeklisThe first one is a rigorous proof of the Landauer-Büttiker formula, and the second one concerns resonant quantum transport. The detailed results are in [2]. In the last section we present the results of som numerical computations on a model system. Concerning the literature, then see the starting point of our work [6].
