Observing Atomic Collapse Resonances in Artificial Nuclei on Graphene
Yang Wang, Dillon Wong, Andrey V. Shytov +10
Relativistic quantum mechanics predicts that when the charge of a superheavy atomic nucleus surpasses a certain threshold, the resulting strong Coulomb field causes an unusual atom…
Electronic and plasmonic phenomena at graphene grain boundaries
Z. Fei, A. S. Rodin, W. Gannett +13
Graphene, a two-dimensional honeycomb lattice of carbon atoms, is of great interest in (opto)electronics and plasmonics and can be obtained by means of diverse fabrication techniqu…
Charge-Carrier Screening in Single-Layer Graphene
David A. Siegel, William Regan, Alexei V. Fedorov +2
The effect of charge-carrier screening on the transport properties of a neutral graphene sheet is studied by directly probing its electronic structure. We find that the Fermi veloc…
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…
