WebApr 11, 2024 · Therefore, the Wu model that describes individual graphene alignment under the electric field does not adequately describe the present system. The strong interparticle interaction causes GNP agglomeration, which reduces the polymer/particle interfacial volume and reduces the particles’ ability to improve the composites’ dielectric properties. WebMar 12, 2008 · The observed extraordinarily large energy shift up to 225 meV of the graphene-derived π band peak position for opposite magnetization directions is attributed to a manifestation of the Rashba interaction between spin-polarized electrons in the π band and the large effective electric field at the graphene/Ni interface. Our findings show that ...
