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…
Filling factor dependence of the fractional quantum Hall effect gap
V. S. Khrapai, A. A. Shashkin, M. G. Trokina +5
We directly measure the chemical potential jump in the low-temperature limit when the filling factor traverses the nu = 1/3 and nu = 2/5 fractional gaps in two-dimensional (2D) ele…
Ultra-efficient Cooling in Ferromagnet-Superconductor Microrefrigerators
F. Giazotto, F. Taddei, R. Fazio +1
A promising scheme for electron microrefrigeration based on ferromagnet-superconductor contacts is presented. In this setup, cooling power densities up to 600 nW/m can be ac…
