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.8 p.application/pdfeng(c) The American Physical Society, 1992Física de l'estat sòlidElectrònica quànticaPel·lícules finesTeoria del transportSolid state physicsQuantum electronicsThin filmsTransport theoryinfo:eu-repo/semantics/article88040info:eu-repo/semantics/openAccess
