1/f noise in a dilute GaAs two-dimensional hole system in the insulating phase
G. Deville, R. Leturcq, D. L'Hote +3
We have measured the resistance and the 1/f resistance noise of a two-dimensional low density hole system in a high mobility GaAs quantum well at low temperature. At densities lowe…
Magnetic field symmetry and phase rigidity of the nonlinear conductance in a ring
R. Leturcq, D. Sanchez, G. Gotz +4
We have performed nonlinear transport measurements as a function of a perpendicular magnetic field in a semiconductor Aharonov-Bohm ring connected to two leads. While the voltage-s…
Single-hole transistor in p-type GaAs/AlGaAs heterostructures
Boris Grbic, Renaud Leturcq, Klaus Ensslin +2
A single-hole transistor is patterned in a p-type, C-doped GaAs/AlGaAs heterostructure by AFM oxidation lithography. Clear Coulomb blockade resonances have been observed at T=300 m…
1/f Noise In Low Density Two-Dimensional Hole Systems In GaAs
G. Deville, R. Leturcq, D. L'Hote +3
Two-dimensional electron or hole systems in semiconductors offer the unique opportunity to investigate the physics of strongly interacting fermions. We have measured the 1/f resist…
Probing the Kondo density of states in a three-terminal quantum ring
R. Leturcq, L. Schmid, K. Ensslin +3
We have measured the Kondo effect in a quantum ring connected to three terminals. In this configuration non-linear transport measurements allow to check which lead contributes to t…
