Charge Imbalance and Bilayer 2D Electron Systems at
A. R. Champagne, A. D. K. Finck, J. P. Eisenstein +2
We use interlayer tunneling to study bilayer 2D electron systems at over a wide range of charge density imbalance, , between the two layers. We find that the…
Evidence of a first-order quantum phase transition of excitons in electron double layers
Biswajit Karmakar, Vittorio Pellegrini, Aron Pinczuk +2
Complexity in many-particle systems occurs through processes of qualitative differentiation. These are described by concepts such as emerging states with specific symmetries that a…
Quasiparticle Tunneling in the Fractional Quantum Hall State at ν= 5/2
Iuliana P. Radu, J. B. Miller, C. M. Marcus +3
Theory predicts that quasiparticle tunneling between the counter-propagating edges in a fractional quantum Hall state can be used to measure the effective quasiparticle charge e* a…
Aharonov-Bohm-Like Oscillations in Quantum Hall Corrals
M. D. Godfrey, P. Jiang, W. Kang +4
Experimental study of quantum Hall corrals reveals Aharonov-Bohm-Like (ABL) oscillations. Unlike the Aharonov-Bohm effect which has a period of one flux quantum, , the ABL o…
Shot-Noise-Limited Operation of a Fast Quantum-Point-Contact Charge Sensor
Madhu Thalakulam, W. W. Xue, Feng Pan +5
We have operated a quantum point contact (QPC) charge detector in a radio frequency (RF) mode that allows fast charge detection in a bandwidth of tens of megahertz. We find that th…
High Resolution Spectroscopy of Two-Dimensional Electron Systems
O. E. Dial, R. C. Ashoori, L. N. Pfeiffer +1
Spectroscopic methods involving the sudden injection or ejection of electrons in materials are a powerful probe of electronic structure and interactions. These techniques, such as…
