A molecular state of correlated electrons in a quantum dot
Sokratis Kalliakos, Massimo Rontani, Vittorio Pellegrini +6
Correlation among particles in finite quantum systems leads to complex behaviour and novel states of matter. One remarkable example is predicted to occur in a semiconductor quantum…
Optical control of energy-level structure of few electrons in AlGaAs/GaAs quantum dots
Sokratis Kalliakos, Vittorio Pellegrini, Cesar Pascual Garcia +3
Optical control of the lateral quantum confinement and number of electrons confined in nanofabricated GaAs/AlGaAs quantum dots is achieved by illumination with a weak laser beam th…
Observation of low-lying excitations of electrons in coupled quantum dots
Cesar Pascual Garcia, Sokratis Kalliakos, Vittorio Pellegrini +4
Tunneling excitations of electrons in dry-etched modulation-doped AlGaAs/GaAs coupled quantum dots (QDs) are probed by resonant inelastic light scattering. A sequence of intra- and…
Evidence of correlation in spin excitations of few-electron quantum dots
Cesar Pascual Garcia, Vittorio Pellegrini, Aron Pinczuk +6
We report inelastic light scattering measurements of spin and charge excitations in nanofabricated AlGaAs/GaAs quantum dots with few electrons. A narrow spin excitation peak is obs…
