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…
