Virgilio Niño Física, Astronomía y Matemáticas Magnetic field wave superconductivity Zero bias conductance peak Through the analytic solutions of the Bogoliubov de Gennes (BdG) equations the effect of a static and homogeneousmagnetic field applied parallel to the interface of an NIS (N: Normal metal, S: superconductor andI: Insulator) junction on the differential conductance is calculated. For a dxy - symmetry we obtain zero biasconductance peak that can be split by a magnetic field. The shift of the zero bias conductance peak depends onthe spread (b) of the tunneling electrons in k space, on the magnitude of the applied field H and on the ratiobetween the Fermi energy of the superconductor and the normal region, EFS=EFN. Finally we estimate theminimum value of the magnetic field, Hmin, that splits the zero bias conductance peak. In general Hmin dependson b, EFS=EFN, the strength of the insulating barrier Z and on the temperature T. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436578 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 |
