Raman sensitivity to crystal structure in InAs nanowires
Jaya Kumar Panda, Anushree Roy, Achintya Singha +4
We report a combined electron transmission and Raman spectroscopy study of InAs nanowires. We demonstrate that the temperature dependent behavior of optical phonon energies can be…
Probing the spin states of three interacting electrons in quantum dots
Andrea Gamucci, Vittorio Pellegrini, Achintya Singha +4
We observe a low-lying sharp spin mode of three interacting electrons in an array of nanofabricated AlGaAs/GaAs quantum dots by means of resonant inelastic light scattering. The fi…
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…
