Документ Tunneling conductance of the s – wave and d- wave pairing superconductive graphene – normal graphene junction(2019) Korol, AnatoliyWithin the framework of the Blonder – Tinkham-Klapwijk formalism we calculate and analyze the conductance of the normal graphene – s-wave and independently d-wave pairing superconductive graphene junction. The eigenfunctions, the Andreev and the normal reflection rates are obtained by solving the Dirac – Bogoliubov – de Gennes equations. We consider the options of gapless and gapped graphene for both cases: – s-wave and independently d-wave.Документ Conductivity of the junction: d-wave pairing superconductive graphene — normal graphene with different Fermi velocity(2018) Korol, Anatoliy; Medved, Nataliya; Vyshniak, Volodymyr; Litvynchuk (Vorontsova), SvitlanaIn recent years, much attention has been paid to the study of graphene and various graphene-based structures. This is due to non-trivial properties of graphene, such as a linear dispersion law for the quasi-particles, whose behavior at low energies is described by an equation similar to the DiracWeyl one, unusual quantum Hall effect, the property of chirality, the Klein tunneling, high mobility, ballistic transport etc. [1, 2]. It should also be borne in mind that graphene is a promising material in modern electronics in terms of replacing the silicon technology, the development of which has reached its limit, for the graphene one. One of the priority directions is to study the various possibilities of controlling the energy spectrum of the graphene-based structures.
