  1. ECE 606 L17.3: Transport - Carrier Concentration from Hall Effect

    20 Jul 2023 | | Contributor(s):: Gerhard Klimeck

  2. 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...

  3. 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...

  4. How Plasmonic Materials Make Light Work at Nanoscale

  5. Nanoscale NMR Studies of Topological Insulators, Crystalline Insulators and Dirac Semimetals

    22 May 2019 | | Contributor(s):: Louis Bouchard

    In this talk, we will review recent advances in experimental techniques to study the electronic and magnetic properties of such topological materials.  Among the novel techniques, we shall discuss radioactive ion beam spectroscopy and nuclear magnetic resonance.   Our group has...

  6. 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...

  7. 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...

  8. 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...

  15. 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...

  16. 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...
