摘要：
We investigate the spin-dependent Fano resonance in an impurity-doped graphene sheet coupled to ferromagnetic (FM) leads at low temperatures. By the nonequilibrium Green's function theory, we calculate the linear conductance of the system, which possesses a different Fano structure both in the parallel and anti-parallel configuration of the FM leads. The results come from the quantum interference between resonant and nonresonant processes in the system. Our studies indicate that the system is an ideal platform to investigate the Fano physics, even in some relevant experiments. (C) 2013 AIP Publishing LLC.
