Graphene-quantum dot hybrid optoelectronics at visible wavelengths
(American Chemical Society, 2018-06)
With exceptional electronic and gate-tunable optical properties, graphene provides new possibilities for active nanophotonic devices. Requirements of very large carrier density modulation, however, limit the operation of ...
Effects of long-range disorder and electronic interactions on the optical properties of graphene quantum dots
(American Physical Society, 2017-01)
We theoretically investigate the effects of long-range disorder and electron-electron interactions on the optical properties of hexagonal armchair graphene quantum dots consisting of up to 10 806 atoms. The numerical ...
Theory of optical properties of graphene quantum dots
We present here a theory of the optical properties of graphene quantum dots (GQDs) with tunable band gaps by lateral size confinement, from UV to THz. Starting from the Hartree-Fock ground state, we construct the correlated ...
