Zero-Bias Anomalies in Narrow Tunnel Junctions in the Quantum Hall Regime
P. Jiang, C. -C. Chien, I. Yang +4
We report on the study of cleaved-edge-overgrown line junctions with a serendipitously created narrow opening in an otherwise thin, precise line barrier. Two sets of zero-bias anom…
Interaction Effects and Pseudogap in Two-Dimensional Lateral Tunnel Junctions
P. Jiang, I. Yang, W. Kang +3
Tunneling characteristics of a two-dimensional lateral tunnel junction (2DLTJ) are reported. A pseudogap on the order of Coulomb energy is detected in the tunneling density of stat…
Tunneling between Two Quantum Hall Droplets
Inseok Yang, Woowon Kang, Loren Pfeiffer +2
We report on tunneling experiment between two quantum Hall droplets separated by a nearly ideal tunnel barrier. The device is produced by cleaved edge overgrowth that laterally jux…
Quantum Hall line junction with impurities as a multi-slit Luttinger liquid interferometer
I. Yang, W. Kang, L. N. Pfeiffer +4
We report on quantum interference between a pair of counterpropagating quantum Hall edge states that are separated by a high quality tunnel barrier. Observed Aharonov-Bohm oscillat…
Cascade of Quantum Phase Transitions in Tunnel-Coupled Edge States
I. Yang, W. Kang, K. W. Baldwin +2
We report on the cascade of quantum phase transitions exhibited by tunnel-coupled edge states across a quantum Hall line junction. We identify a series of quantum critical points b…
Vertical Confinement and Evolution of Reentrant Insulating Transition in the Fractional Quantum Hall Regime
I. Yang, W. Kang, S. T. Hannahs +2
We have observed an anomalous shift of the high field reentrant insulating phases in a two-dimensional electron system (2DES) tightly confined within a narrow GaAs/AlGaAs quantum w…
