Theoretical prediction of perfect spin filtering at interfaces between close-packed surfaces of Ni or Co and graphite or graphene
V. M. Karpan, P. A. Khomyakov, A. A. Starikov +6
The in-plane lattice constants of close-packed planes of fcc and hcp Ni and Co match that of graphite almost perfectly so that they share a common two dimensional reciprocal space.…
Graphite and graphene as perfect spin filters
V. M. Karpan, G. Giovannetti, P. A. Khomyakov +6
Based upon the observations (i) that their in-plane lattice constants match almost perfectly and (ii) that their electronic structures overlap in reciprocal space for one spin dire…
First-principles scattering matrices for spin-transport
K. Xia, M. Zwierzycki, M. Talanana +2
Details are presented of an efficient formalism for calculating transmission and reflection matrices from first principles in layered materials. Within the framework of spin densit…
