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'. Tīmeklis2024. gada 10. janv. · A Landauer-Buttiker analysis of measurements on multi-terminal samples allows us to quantitatively assess edge state scattering. We interpret these results as signatures of the predicted topological phase at charge neutrality. Subjects: Mesoscale and Nanoscale Physics ...

TīmeklisAbstract. We give a short presentation of two recent results. The 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 some numerical computations on a model system.

In general, carriers will exhibit ballistic conduction when where is the length of the active part of the device (e.g., a channel in a MOSFET). is the mean free path for the carrier which can be given by Matthiessen's rule, written here for electrons: where • is the electron-electron scattering length, 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 …
