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…
Streaming Batch Eigenupdates for Hardware Neuromorphic Networks
Brian D. Hoskins, Matthew W. Daniels, Siyuan Huang +5
Neuromorphic networks based on nanodevices, such as metal oxide memristors, phase change memories, and flash memory cells, have generated considerable interest for their increased…
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…
Strain Engineering a Charge Density Wave Phase in Transition Metal Dichalcogenide 1T-VSe
Duming Zhang, Jeonghoon Ha, Hongwoo Baek +10
We report a rectangular charge density wave (CDW) phase in strained 1T-VSe thin films synthesized by molecular beam epitaxy on c-sapphire substrates. The observed CDW structure…
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…
