Symmetry-Adapted Tight-Binding Electronic Structure Analysis of Carbon Nanotubes with Defects, Kinks, Twist, and Stretch
Soumya Mukherjee, Hossein Pourmatin, Yang Wang +2
This paper applies a symmetry-adapted method to examine the influence of deformation and defects on the electronic structure and band structure in carbon nanotubes. First, the symm…
Microscopy of hydrogen and hydrogen-vacancy defect structures on graphene devices
Dillon Wong, Yang Wang, Wuwei Jin +8
We have used scanning tunneling microscopy (STM) to investigate two types of hydrogen defect structures on monolayer graphene supported by hexagonal boron nitride (h-BN) in a gated…
Spatially resolving density-dependent screening around a single charged atom in graphene
Dillon Wong, Fabiano Corsetti, Yang Wang +8
Electrons in two-dimensional graphene sheets behave as interacting chiral Dirac fermions and have unique screening properties due to their symmetry and reduced dimensionality. By u…
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…
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…
Gate-Controlled Ionization and Screening of Cobalt Adatoms on a Graphene Surface
Victor W. Brar, Regis Decker, Hans-Michael Solowan +9
We describe scanning tunneling spectroscopy (STS) measurements performed on individual cobalt (Co) atoms deposited onto backgated graphene devices. We find that Co adatoms on graph…
