Webrespectively, of one electron at site i, orbital α, and spin s. We focus on neutral graphene; thus, no doping effects are addressed. SOC effects are included by adding an atomiclike term H SO to the H 0 Hamiltonian. Assuming that the most important contribution of the crystal potential to the spin-orbit coupling is close to the cores, the H Webnisms of spin scattering [10–14]. Second, the low intrinsic spin-orbit coupling values [9,15] render the conventional SHE mechanisms ineffective, depriving graphene spin-tronics of a crucial control knob for spin transport.
