Fermi velocity engineering in graphene by substrate modification
Choongyu Hwang, David A. Siegel, Sung-Kwan Mo +5
The Fermi velocity is one of the key concepts in the study of a material, as it bears information on a variety of fundamental properties. Upon increasing demand on the device appli…
Electrical Control of Plasmon Resonance with Graphene
Jonghwan Kim, Hyungmok Son, David J. Cho +7
Surface plasmon, with its unique capability to concentrate light into sub-wavelength volume, has enabled great advances in photon science, ranging from nano-antenna and single-mole…
Mapping Dirac Quasiparticles near a Single Coulomb Impurity on Graphene
Yang Wang, Victor W. Brar, Andrey V. Shytov +6
The response of Dirac fermions to a Coulomb potential is predicted to differ significantly from the behavior of non-relativistic electrons seen in traditional atomic and impurity s…
Raman spectroscopy study of rotated double-layer graphene: Misorientation-angle dependence of electronic structure
Kwanpyo Kim, Sinisa Coh, Liang Z. Tan +7
We present a systematic Raman study of unconventionally-stacked double-layer graphene, and find that the spectrum strongly depends on the relative rotation angle between layers. Ro…
