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…
Electronic implementations of Interaction-Free Measurements
L. Chirolli, E. Strambini, V. Giovannetti +5
Three different implementations of interaction-free measurements (IFMs) in solid-state nanodevices are discussed. The first one is based on a series of concatenated Mach-Zehnder in…
Singlet-triplet transition in a few-electron lateral InGaAs-InAlAs quantum dot
F. Deon, V. Pellegrini, F. Carillo +4
The magnetic-field evolution of Coulomb blockade peaks in lateral InGaAs/InAlAs quantum dots in the few-electron regime is reported. Quantum dots are defined by gates evaporated on…
Coherent detection of electron dephasing
E. Strambini, L. Chirolli, V. Giovannetti +4
We show that an Aharonov-Bohm (AB) ring with asymmetric electron injection can act as a coherent detector of electron dephasing. The presence of a dephasing source in one of the tw…
Polaronic Excitons in ZnCdSe/ZnSe Quantum Wells
A. De Nardis, V. Pellegrini, R. Colombelli +3
We present a detailed investigation of excitonic absorption in quantum wells under the application of a perpendicular magnetic field. The large energy s…
