Long-Range Magnetic Exchange Pathways in Complex Clusters from First-Principles
Dian-Teng Chen, Jia Chen, Xiang-Guo Li +3
This work builds a bridge between density functional theory (DFT) and model interpretations of Anderson's superexchange theory by constructing a -- model with DFT Wannier…

Electron transport in graphene/graphene side-contact junction by plane-wave multiple scattering method
Xiang-Guo Li, Iek-Heng Chu, X. -G. Zhang +1
Electron transport in graphene is along the sheet but junction devices are often made by stacking different sheets together in a "side-contact" geometry which causes the current to…
