Graphene Nanoribbons Transport Properties Calculation

Original language description

The spin-dependent exchange-correlation potential is approximated within the generalized gradient approximation using the QuantumWise toolkit ATK, which employs local numerical double-zeta polarized basis orbitals. The spin-dependent transport propertiesof the electrode-device-electrode geometry were calculated by means of non-equilibrium Green's function formalism as implemented in ATK. Band structures calculated by the DFT were compared with results of the semi-empirical method (Extended Huckel model). Our results show that GNRs with the constrictions exhibit novel transport properties. The horizontal layout of the GNR constrictions determines main features important for electrical and spintronic applications of these structures. The constrictions could be realized by means of local anodic oxidation using scanning probe microscope.
