Online Presentations (1-6 of 6)

  1. Heat Under the Microscope:
 Uncovering the Microscopic Processes that Govern 
Thermal Transport

    04 Oct 2016 | | Contributor(s):: Austin Minnich

    n this talk, I will describe our efforts to uncover the microscopic processes that govern thermal transport by phonons. In particular, I will describe how our advances in computation and experiment have enabled the first direct measurements of thermal phonon transmission coefficients at solid...

  2. Unified View of Electron and Phonon Transport

    10 Nov 2015 | | Contributor(s):: Mark Lundstrom, Jesse Maassen

    A simple, unified view of electron and phonon transport is presented. Similarities and differences are identified, and new insights that come from addressing phonon transport from an electron transport perspective will be discussed.

  3. From Single-Stage to Device-Level Simulation of Coupled Electron and Phonon Transport in Quantum Cascade Lasers

    02 Nov 2015 | | Contributor(s):: Irena Knezevic

    IWCE 2015 presentation.  Abstract and more information to be added at a later date.

  4. Thermoelectric Energy Conversion: Transport, Materials, and Systems

    05 Dec 2012 | | Contributor(s):: Gang Chen

    his talk will start with an introduction to thermoelectric effects, and move on to discuss ways to understand and engineer electron and phonon transport in thermoelectric materials to improve the figure of merit. On phonon transport, thermal conductivity spectroscopy and coherent heat conduction...

  6. Limits of Thermal Processes and their Implications on Efficient Energy Utilization

    27 Oct 2010 | | Contributor(s):: Arunava Majumdar

    About 90 percent of the world’s energy use involves thermal processes – thermal engines to generate mechanical power; heating and cooling in buildings; heating involved in manufacturing of steel, cement, glass, petrochemicals etc. To identify opportunities for improving current technologies or...
