QUANTUM OSCILLATIONS AND THE ELECTRONIC TRANSPORT PROPERTIES IN MULTICHAIN NANORINGS

摘要

We consider a system of multichain nanorings in static electric and magnetic field. The magnetic field induces characteristic phase changes. These phase shifts produce interference phenomena in the case of nanosystems for which the coherence length is larger than the sample dimension. We obtain energy solutions that are dependent on the number of sites N_α characterizing a chain, of phase on the phase φ_α and on the applied voltage. We found rich oscillations structures exhibited by the magnetic flux and we established the transmission probability. This proceeds by applying Landauer conductance formulae which opens the way to study electronic transport properties.
