Delocalized-localized transition in a semiconductor two-dimensional honeycomb lattice
G. De Simoni, A. Singha, M. Gibertini +7
We report the magneto-transport properties of a two-dimensional electron gas in a modulation-doped AlGaAs/GaAs heterostructure subjected to a lateral potential with honeycomb geome…

Electron density distribution and screening in rippled graphene sheets
Marco Gibertini, Andrea Tomadin, Marco Polini +2
Single-layer graphene sheets are typically characterized by long-wavelength corrugations (ripples) which can be shown to be at the origin of rather strong potentials with both scal…
