Tunneling Spectroscopy of Quantum Hall States in Bilayer Graphene PN Networks
Ke Wang, Achim Harzheim, Ji Ung Lee +3
Two dimensional electronic systems under strong magnetic field form quantum Hall (QH) edge states, which propagate along the boundary of a sample with a dissipationless current. En…
Current partition at zero-line intersection of quantum anomalous Hall topologies
Yafei Ren, Junjie Zeng, Ke Wang +2
At the interface between two-dimensional materials with different topologies, topologically protected one-dimensional states (also named as zero-line modes) arise. Here, we focus o…
Guided Modes of Anisotropic van der Waals Materials Investigated by Near-Field Scanning Optical Microscopy
Daniel Wintz, Kundan Chaudhary, Ke Wang +11
Guided modes in anisotropic two-dimensional van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method in…
Perfectly Conducting Graphene Electronic Waveguide with Curved Channels
Vahid Mosallanejad, Ke Wang, Zhenhua Qiao +1
We theoretically investigate the electronic transport properties of curved graphene waveguides by employing non-equilibrium Green's function techniques. We systematically study the…
Gate tunable current partition in graphene based topological zero lines
Yafei Ren, Ke Wang, Xinzhou Deng +3
We demonstrate new mechanisms for gate tunable current partition at topological zero-line intersections in a graphene-based current splitter. Based on numerical calculations of the…
