Title: | Electronic transport in quantum waveguide systems with attached stubs | Authors: | Nikolić K. Šordan R. |
Issue Date: | 1-Jan-1998 | Journal: | Physical Review B - Condensed Matter and Materials Physics | Abstract: | Single-mode quantum transmission properties of a quantum waveguide system with attached stubs are studied in the ballistic regime. The formation of energy bands is achieved in the case of periodic structure mainly around the energies where a single stub possesses antiresonances. A single defect in the otherwise periodic structure introduces a resonant (or an antiresonant) state. We find that this state is not an exponentially localized state, and is not a Fano-type resonance (although it originates from it), but more a well-known Lorentzian-shaped Breit-Wigner transmission resonance. When this state falls in the energy band, then it forms an antiresonance. A strong magnetic field creates additional quasibound states. © 1998 The American Physical Society. | URI: | https://open.uns.ac.rs/handle/123456789/16045 | ISSN: | 10980121 | DOI: | 10.1103/PhysRevB.58.9631 |
