摘要: The quantum transport properties of a non-interacting mesoscopic ring sandwiched between two metallic electrodes are investigated by the use Green's function technique. Here, we introduce parametric approach, based on tight-binding model to study these properties. electronic focused in three aspects: (a) geometry ring, (b) coupling strength with and (c) magnetic flux threaded ring.
