| contents | Square-Gradient Scattering Mechanism in Surface-CorrugatedWaveguides F. M. Izrailev M. Rendón N. M. Makarov Física, Astronomía y Matemáticas Surface scattering Electronic transport in quantum wires Wave propagation in random guiding media In this work we study the surface scattering mechanisms from rough surfaces of a multimode quasi-1Dwaveguide (conducting quantum wires). The square-gradient scattering mechanism, which was missed in existingstudies of the transport through surface-corrugated waveguides, is discovered. The main attention is paidto the interplay between the new mechanism and the known one, as well as its effect on the waveguide transportproperties. For any value of the roughness height s, the square-gradient terms in the expression for thewave-scattering length (electron mean-free path) are dominant, provided the correlation length Rc of the surfacedisorder is small enough. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436546 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
