▎ 摘　　要

In this article we highlight recent work in which we computed the spin unpolarized coherent electron transport through two terminal nanoscale graphene/metal junctions using equilibrium Green's functions coupled to Density functional theory, capturing in detail the important electronic effects created at metal/graphene interfaces. In those calculations the metal contacts may or may not bind covalently to graphene. Along the way, connections to other models for coherent transport on graphene junctions with metal contacts are given as well. As it may be known, the computation of the electronic dispersion at the interface between graphene and binding metals in a transport setup is extremely time-consuming, and it is perhaps for this reason that effects of metals are neglected or are captured only qualitatively in the theoretical and computational modeling of graphene devices. It thus seems to us that a methodology to go past this stumbling block may be well-received. We outline an approach to obtain tight-binding parameters describing the electronic dispersion at interfaces between titanium leads and graphene. The deployment of those tight-binding parameters is new, and it constitutes the main contribution on the present paper.
