   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...

5. Many Body Effects on Optical Properties of Graphene

   13 Oct 2016 | | Contributor(s):: Subhasis Ghosh

   Graphene, a two-­dimensional (2D) material shows remarkable optical and electronic properties, such as a linear energy dispersion, chirality and half-­integer quantum Hall effect. Multilayer graphene flakes, held together by weak van der Waals forces have also attracted attention due to...

16. Symmetry, Dimension, and Spin: Understanding transport in 2D 'phosphorene'

    02 Mar 2015 | | Contributor(s):: Ian Appelbaum

    Despite its low atomic number and inversion symmetry, recent electronic measurements demonstrate that (group-IV) graphene has a greatly disappointing spin lifetime, corroborated by theory showing strong spin-flip scattering by flexural (out-of-plane) phonons. There exists a class of graphene-like...
