Spin exchange interaction with tunable range between graphene quantum dots
Spin exchange interaction tunable graphene quantum dots
2010/11/22
We study the spin exchange between two electrons localized in separate quantum dots in graphene.The electronic states in the conduction band are coupled indirectly by tunneling to a common continuum o...
Edge stability, reconstruction, zero-energy states and magnetism in triangular graphene quantum dots with zigzag edges
Edge stability magnetism zigzag edges
2010/11/17
We present the results of ab-initio density functional theory based calculations of the stability and reconstruction of zigzag edges in triangular graphene quantum dots. We show that, while the recons...
