摘要
We demonstrate theoretically the possibility of producing a pure spin current in graphene by filtering the charge from a spin- polarized electric current. To achieve this effect, which is based on the recently predicted property of specular Andreev reflection in graphene, we propose two possible device structures containing normal- superconductor junctions.
