Classical-to-stochastic Coulomb blockade cross-over in aluminum arsenide wires
J. Moser, S. Roddaro, D. Schuh +3
We report low-temperature differential conductance measurements in aluminum arsenide cleaved-edge overgrown quantum wires in the pinch-off regime. At zero source-drain bias we obse…
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…
Aluminum arsenide cleaved-edge overgrown quantum wires
J. Moser, T. Zibold, S. Roddaro +5
We report conductance measurements in quantum wires made of aluminum arsenide, a heavy-mass, multi-valley one-dimensional (1D) system. Zero-bias conductance steps are observed as t…
Anti-crossings of spin-split Landau levels in an InAs two-dimensional electron gas with spin-orbit coupling
W. Desrat, F. Giazotto, V. Pellegrini +5
We report tilted-field transport measurements in the quantum-Hall regime in an InAs/In_0.75Ga_0.25As/In_0.75Al_0.25As quantum well. We observe anti-crossings of spin-split Landau l…
Particle-hole symmetric Luttinger liquids in a quantum Hall circuit
Stefano Roddaro, Vittorio Pellegrini, Fabio Beltram +2
We report current transmission data through a split-gate constriction fabricated onto a two-dimensional electron system in the integer quantum Hall (QH) regime. Split-gate biasing…
