Electrons imitating light: Frustrated supercritical collapse in charged arrays on graphene
Jiong Lu, Hsin-Zon Tsai, Alpin N. Tatan +10
The photon-like electronic dispersion of graphene bestows its charge carriers with unusual confinement properties that depend strongly on the geometry and strength of the surroundi…
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…
Visualization and Control of Single Electron Charging in Bilayer Graphene Quantum Dots
Jairo Velasco, Juwon Lee, Dillon Wong +9
Graphene p-n junctions provide an ideal platform for investigating novel behavior at the boundary between electronics and optics that arise from massless Dirac fermions, such as wh…
