Graphene spintronics: the role of ferromagnetic electrodes.
NANO LETTERS, no. 1 (2011): 151-155
SCOPUS
摘要
We report a first principles study of spin transport under finite bias through a graphene-ferromagnet (FM) interface, where FM = Co(111), Ni(111). The use of Co and Ni electrodes achieves spin efficiencies reaching 80% and 60%, respectively. This large spin filtering results from the materials specific interaction between graphene and the...更多
