Electron transport in bilayer graphene nano constrictions patterned using AFM nanolithography
Robert W. Rienstra, Nishat Sultana, En-Min Shih +7
Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (L…
Edge Channels of Broken-Symmetry Quantum Hall States in Graphene probed by Atomic Force Microscopy
Sungmin Kim, Johannes Schwenk, Daniel Walkup +12
The quantum Hall (QH) effect, a topologically non-trivial quantum phase, expanded and brought into focus the concept of topological order in physics. The topologically protected qu…
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…
Programmable Extreme Pseudomagnetic Fields in Graphene by a Uniaxial Stretch
Shuze Zhu, Joseph A. Stroscio, Teng Li
Many of the properties of graphene are tied to its lattice structure, allowing for tuning of charge carrier dynamics through mechanical strain. The graphene electro-mechanical coup…
Creating Nanostructured Superconductors On Demand by Local Current Annealing
Hongwoo Baek, Jeonghoon Ha, Duming Zhang +10
Superconductivity results from a Bose condensate of Cooper-paired electrons with a macroscopic quantum wavefunction. Dramatic effects can occur when the region of the condensate is…
