Local transport in a disorder-stabilized correlated insulating phase
M. Baenninger, A. Ghosh, M. Pepper +4
We report the experimental realization of a correlated insulating phase in 2D GaAs/AlGaAs heterostructures at low electron densities in a limited window of background disorder. Thi…
Acoustic charge transport in n-i-n three terminal device
Marco Cecchini, Giorgio De Simoni, Vincenzo Piazza +3
We present an unconventional approach to realize acoustic charge transport devices that takes advantage from an original input region geometry in place of standard Ohmic input cont…
Effects of Zeeman spin splitting on the modular symmetry in the quantum Hall effect
D. R. Hang, R. B. Dunford, Gil-Ho Kim +7
Magnetic-field-induced phase transitions in the integer quantum Hall effect are studied under the formation of paired Landau bands arising from Zeeman spin splitting. By investigat…
Conductance quantization and the 0.7x2e2/h conductance anomaly in one-dimensional hole systems
R. Danneau, W. R. Clarke, O. Klochan +5
We have studied ballistic transport in a 1D channel formed using surface gate techniques on a back-gated, high-mobility, bilayer 2D hole system. At millikelvin temperatures, robust…
Zero-bias anomaly and Kondo-assisted quasi-ballistic 2D transport
Arindam Ghosh, Matthew Wright, Christophe Siegert +4
Nonequilibrium transport measurements in mesoscopic quasi-ballistic 2D electron systems show an enhancement in the differential conductance around the Fermi energy. At very low tem…
Measurements of Composite Fermion Conductivity Dependence on Carrier Density
C. -T. Liang, M. Y. Simmons, D. A. Ritchie +1
We present the first experimental study of the carrier density dependence of the composite fermion conductivity at Landau level filling factors and $ν= {3/…
