Selective Manipulation and Tunneling Spectroscopy of Broken-Symmetry Quantum Hall States in a Hybrid-edge Quantum Point Contact
Wei Ren, Xi Zhang, Jaden Ma +4
We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of e…
Gate-tunable Veselago Interference in a Bipolar Graphene Microcavity
Xi Zhang*, Wei Ren*, Elliot Bell +6
The relativistic charge carriers in monolayer graphene can be manipulated in manners akin to conventional optics (electron-optics): angle-dependent Klein tunneling collimates an el…
Unexpected two-fold symmetric superconductivity in few-layer NbSe
Alex Hamill, Brett Heischmidt, Egon Sohn +13
Two-dimensional transition metal dichalcogenides (TMDs) have been attracting significant interest due to a range of properties, such as layer-dependent inversion symmetry, valley-c…
Image polaritons in boron nitride for extreme polariton confinement with low losses
In-Ho Lee, Mingze He, Xi Zhang +8
Polaritons in two-dimensional materials provide extreme light confinement that is difficult to achieve with metal plasmonics. However, such tight confinement inevitably increases o…
Correlated Insulating States and Transport Signature of Superconductivity in Twisted Trilayer Graphene Moiré of Moiré Superlattices
Kan-Ting Tsai, Xi Zhang, Ziyan Zhu +5
Layers of two-dimensional materials stacked with a small twist-angle give rise to beating periodic patterns on a scale much larger than the original lattice, referred to as a moiré…
