Fundamentals of Current Flow
30 Jan 2022 | | Contributor(s):: Supriyo Datta
Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat...

2D Valley-Spin Transport in Transition Metal Dichalcogenides
07 May 2020 | | Contributor(s):: Zhihong Chen
In this talk, we first report that valley current can be electrically induced and detected through the valley Hall effect and inverse valley Hall effect, respectively, in monolayer molybdenum disulfide. We compare temperature and channel length dependence of non-local electrical signals in...

Photonic Structures with Topological Robustness: from Classical to Quantum
09 Jan 2017 | | Contributor(s):: Mohammad Hafezi
In this talk, I demonstrate how similar physics can be observed for photons; specifically, how various quantum Hall Hamiltonians can be simulated in an optical platform. I report on the first observation of topological photonic edge state using silicon-on-insulator technology and our recent...

Few-Body Insights Into the Quantum Hall Problem
05 Jan 2016 |
This talk will summarize insights that emerge from theoretically treating a finite number of (3-8) electrons confined to a two-dimensional plane with a magnetic field oriented transversely. This is the prototype system of strongly-correlated electrons in condensed matter physics, which...

Graphene Nanoribbon Hall Effect
Q&A|Closed | Responses: 2
Hello
I'm new here in the community, and I am currently working on the Hall effect of GNRs.
My question is that, compared to the Hall effect in Graphene, how do I account...

Near-Equilibrium Transport: Fundamentals and Applications
28 Jul 2011 | | Contributor(s):: Mark Lundstrom
Engineers and scientists working on electronic materials and devices need a working knowledge of "near-equilibrium" (also called "linear" or "low-field") transport. The term "working knowledge" means understanding how to use theory in practice. Measurements...

Coupled Effect of Strain and Magnetic Field on Electronic Bandstructure of Graphene
07 Dec 2010 | | Contributor(s):: yashudeep singh
We explore the possibility of coupling between planar strain and perpendicular magnetic field on electronic bandstructure of graphene. We study uni-axially, bi-axially and shear strained graphene under magnetic field. In line with Rammal’s formalism using nearest neighbor tight binding scheme we...
