Ferreira Física, Astronomía y Matemáticas Single Magnetic impurities Transport properties wall carbon nanotubes We are interested in studying the transport properties of metallic single-wall carbon nanotubes (SWCNTs)with isolated magnetic impurities. We consider a metallic zigzag SWCNT in the form of an infinitely longcylinder of diameter D, connected by two metallic electrodes under a bias voltage E, with a magnetic impuritylocated on its surface. To describe the Kondo resonance we employ an impurity version of the atomic model,previously developed to study the Kondo insulator properties in the lattice case. We calculate the approximateGreens functions of the impurity Anderson model by employing the exact solution of the atomic limit of theAnderson model, where we use the completeness condition to choose the position of the chemical potential. Weconsider the SWCNT Greens functions in a tight-binding approach. We calculate density of states curves thatcharacterize well the structure of the Kondo peak and we also present the dependence of the conductance withthe diameter of the SWCNT 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436345 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.2A Vol.36 |
