  1. SDMS L4.03: Mobility Modeling

    Presentation Materials | 09 Oct 2023 | Contributor(s):: Dragica Vasileska

  2. Atomistic Green’s Functions: The Beauty of Self-energies

    Online Presentations | 28 Oct 2020 | Contributor(s):: Tillmann Christoph Kubis

    This presentation gives an introduction to NEGF. It will be explained how self-energies cause NEGF to fundamentally differ from most other quantum methods. Atomistic examples of phonon and impurity scattering self-energies agree quantitatively with experiments.

  3. NEMO5 and 2D Materials: Tuning Bandstructures, Wave Functions and Electrostatic Screening

    Online Presentations | 19 Oct 2016 | Contributor(s):: Tillmann Christoph Kubis

    In this talk, I will briefly discuss the MLWF approach and compare it to DFT and atomistic tight binding. Initial results using the MLWF approach for 2D material based devices will be discussed and compared to experiments. These results unveil systematic band structure changes as functions of the...

  4. Spectral phonon relaxation time calculation tool by using normal mode analysis based on molecular dynamics

    Tools | 19 Jan 2016 | Contributor(s):: Tianli Feng, Divya Chalise, Xiulin Ruan

    Calculate the spectral phonon relaxation time in solids based on molecular dynamics.

  5. Lorentzian fitting tool for phonon spectral energy density and general use

    Tools | 20 Oct 2015 | Contributor(s):: Tianli Feng, Xiulin Ruan

    Fit a general data set (or specially the phonon spectral energy density) as a Lorentzian function to obtain the peak position (or phonon frequency) and full width at half maximum (or relaxation time).
