Effective one-dimensional square well for two-dimensional quantum wires Wu, H. (Hua) Sprung, Donald W. L. Martorell Domenech, Juan Física de l'estat sòlid Electrònica quàntica Pel·lícules fines Teoria del transport Solid state physics Quantum electronics Thin films Transport theory The symmetrical two-dimensional quantum wire with two straight leads joined to an arbitrarily shaped interior cavity is studied with emphasis on the single-mode approximation. It is found that for both transmission and bound-state problems the solution is equivalent to that for an energy-dependent one-dimensional square well. Quantum wires with a circular bend, and with single and double right-angle bends, are examined as examples. We also indicate a possible way to detect bound states in a double bend based on the experimental setup of Wu et al. 2009-11-03T08:46:24Z 2009-11-03T08:46:24Z 1992 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0163-1829 https://hdl.handle.net/2445/9944 88040 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevB.45.11960 Physical Review B, 1992, vol. 45, núm. 20, p. 11960-11967. http://dx.doi.org/10.1103/PhysRevB.45.11960 (c) The American Physical Society, 1992 info:eu-repo/semantics/openAccess 8 p. application/pdf The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
