Spin Valve Effect in ZigZag Graphene Nanoribbons by Defect Engineering
Sankaran Lakshmi, Stephan Roche, Gianaurelio Cuniberti
We report on the possibility for a spin valve effect driven by edge defect engineering of zigzag graphene nanoribbons. Based on a mean-field spin unrestricted Hubbard model, electr…
Chemically-induced Mobility Gaps in Graphene Nanoribbons: A Route for Upscaling Device Performances
Blanca Biel, François Triozon, X. Blase +1
We report a first-principles based study of mesoscopic quantum transport in chemically doped graphene nanoribbons with a width up to 10 nm. The occurrence of quasibound states rela…
Anomalous Doping Effects on Charge Transport in Graphene Nanoribbons
Blanca Biel, X. Blase, François Triozon +1
We present first-principles calculations of quantum transport in chemically doped graphene nanoribbons with a width of up to 4 nm. The presence of boron and nitrogen impurities is…
