    • Disorder density of states in supported graphene 

      Lee, Ji Ung; Sinha, Dhiraj (Journal of Applied Physics, 2014)
      Transport in graphene is impacted by disorder. Disorder, which can occur on supported graphene, manifests as a significant shift in the Fermi level position from the charge neutrality point (Dirac point) and leads to ...

    • Substrate dielectric effects on graphene field effect transistors 

      Hu, Zhaoying; Sinha, Dhiraj Prasad; Lee, Ji Ung; Liehr, Michael (Journal of Applied Physics, 2014)
      Graphene is emerging as a promising material for future electronics and optoelectronics applications due to its unique electronic structure. Understanding the graphene-dielectric interaction is of vital importance for the ...

    • tRNA modification detection using graphene nanopores: A simulation study 

      Onanuga, Khadijah; Begley, Thomas J.; Chen, Alan A.; Ranganathan, Srivathsan V. (MDPI AG, 2017-08-25)
      There are over 100 enzyme-catalyzed modifications on transfer RNA (tRNA) molecules. The levels and identity of wobble uridine (U) modifications are affected by environmental conditions and diseased states, making wobble U ...

    • Understanding magnetic focusing in graphene p-n junctions through quantum modeling 

      LaGasse, Samuel W.; Lee, Ji Ung (Physical Review B, 2017-04-21)
      We present a quantum model which provides enhanced understanding of recent transverse magnetic focusing experiments on graphene p-n junctions. Spatially resolved flow maps of local particle current density show quantum ...
