Spin-up "pristine-like" Dirac cone in bridge-structure graphene on Ni(111)
We report a novel unshifted Dirac cone in energy and in k-space (pristine-like) for the spin-up electrons of experimentally verified bridge-structure of graphene on Ni(111) using density functional theory with van der Waals corrections. Also, we found that the spin-down electrons exhibit a metallic property. This co-existence of semi-metallic and metallic nature of electrons at the Fermi level can pave a way for effective ultra-thin spin-electronic devices such as memory devices, where different scattering of two spin-configurations of electrons is desired.
