Geometric interference in a high-mobility graphene annulus p-n junction device
Son T. Le, Albert F. Rigosi, Joseph A. Hagmann +3
The emergence of interference is observed in the resistance of a graphene annulus pn junction device as a result of applying two separate gate voltages. The observed resistance pat…
Room temperature strain-induced Landau levels in graphene on a wafer-scale platform
P. Nigge, A. C. Qu, É. Lantagne-Hurtubise +14
Graphene is a powerful playground for studying a plethora of quantum phenomena. One of the remarkable properties of graphene arises when it is strained in particular geometries and…
Interaction Driven Quantum Hall Wedding cake-like Structures in Graphene Quantum Dots
Christopher Gutiérrez, Daniel Walkup, Fereshte Ghahari +7
Quantum-relativistic matter is ubiquitous in nature; however it is notoriously difficult to probe. The ease with which external electric and magnetic fields can be introduced in gr…
An On/Off Berry Phase Switch in Circular Graphene Resonators
Fereshte Ghahari, Daniel Walkup, Christopher Gutiérrez +10
The phase of a quantum state may not return to its original value after the system's parameters cycle around a closed path; instead, the wavefunction may acquire a measurable phase…
Visualizing the Charge Density Wave Transition in 2H-NbSe2 in Real Space
S. P. Chockalingam, C. J. Arguello, E. P. Rosenthal +9
We report the direct observation in real space of the charge density wave (CDW) phase transition in pristine 2H-NbSe2 using atomic-resolution scanning tunneling microscopy (STM). W…
Visualizing Individual Nitrogen Dopants in Monolayer Graphene
Liuyan Zhao, Rui He, Kwang Taeg Rim +15
In monolayer graphene, substitutional doping during growth can be used to alter its electronic properties. We used scanning tunneling microscopy (STM), Raman spectroscopy, x-ray sp…
