Two-dimensional Mott-Hubbard electrons in an artificial honeycomb lattice
A. Singha, M. Gibertini, B. Karmakar +8
Electrons in artificial lattices enable explorations of the impact of repulsive Coulomb interactions in a tunable system. We have trapped two-dimensional electrons belonging to a g…
Engineering artificial graphene in a two-dimensional electron gas
M. Gibertini, A. Singha, V. Pellegrini +5
At low energy, electrons in doped graphene sheets behave like massless Dirac fermions with a Fermi velocity which does not depend on carrier density. Here we show that modulating a…
Optical Anisotropy of Electronic Excitations in Elliptical Quantum Dots
Achintya Singha, Vittorio Pellegrini, Sokratis Kalliakos +4
The authors report that anisotropic confining potentials in laterally-coupled semiconductor quantum dots (QDs) have large impacts in optical transitions and energies of inter-shell…
