| contents | Magnetic Field Effects of Double-Walled Carbon Nanotubes M. S. Ferreira A. Latgé D. Grimm Física, Astronomía y Matemáticas Conductance Magnetic field Carbon nanotubes A theoretical discussion of electronic and transport properties of a particular family of double-wall carbonnanotubes, named commensurate structures of the armchair type (n,n)@(2n,2n) is addressed. A single p-bandtight binding hamiltonian is considered and the magnetic field is theoretically described by following the Peierlsapproximation into the hopping energies. Our emphasis is put on investigating the main effects of the geometricalaspects and relative positions of the tubes on the local density of states and on the conductance of the system.By considering intershell interactions between a set of neighboring atoms on the walls of the inner and outertubes, we study the possibility of founding Aharonov-Bohm effects in the DWCNs when a magnetic field isapplied along the axial direction. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436526 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 |
