Tunneling Field-Effect Junctions with WS barrier
Xiang-Guo Li, Yun-Peng Wang, X. -G. Zhang +1
Transition metal dichalcogenides (TMDCs), with their two-dimensional structures and sizable bandgaps, are good candidates for barrier materials in tunneling field-effect transistor…
Spin-flip noise due to nonequilibrium spin accumulation
Liang Liu, Jiasen Niu, Huiqiang Guo +6
When current flows through a magnetic tunnel junction (MTJ), there is spin accumulation at the electrode-barrier interfaces if the magnetic moments of the two ferromagnetic electro…
Electronic resistances of multilayered two-dimensional crystal junctions
Yun-Peng Wang, X. -G. Zhang, J. N. Fry +1
We carry out a layer-by-layer investigation to understand electron transport across metal-insulator-metal junctions. Interfacial structures of junctions were studied and characteri…
Symmetry-dependent electron-electron interaction in coherent tunnel junctions resolved by zero bias anomaly measurements
Liang Liu, Jiasen Niu, Li Xiang +6
We provide conclusive experimental evidence that zero bias anomaly in the differential resistance of magnetic tunnel junctions (MTJs) is due to electron-electron interaction (EEI),…
Friedel Oscillation-Induced Energy Gap Manifested as Transport Asymmetry at Monolayer-Bilayer Graphene Boundaries
Kendal W. Clark, X. -G. Zhang, Gong Gu +4
We show that Friedel charge oscillation near an interface opens a gap at the Fermi energy for electrons with wave vectors perpendicular to the interface. If the Friedel gaps on two…
Coherent electron transport through an azobenzene molecule: A light-driven molecular switch
Chun Zhang, M. -H. Du, H. -P. Cheng +3
We apply a first-principles computational approach to study a light-sensitive molecular switch. The molecule that comprises the switch can convert between a trans and a cis configu…
