Demonstration of a Field-Effect Three-Terminal Electronic Device with an Electron Mobility Exceeding 40 Million cm^2/(Vs)
T. J. Martz-Oberlander, B. Bulgaru, Z. Berkson-Korenberg +6
We report the fabrication and operation of a source-drain-gate three-terminal field-effect electronic device with an electron mobility exceeding cm / (Vs). Seve…
Melting of quantum Hall Wigner and bubble crystals
H. Xia, Qianhui Xu, Jiasen Niu +7
A two-dimensional crystal melts via the proliferation and unbinding of topological defects, yet quantitatively predicting the melting temperature in real systems is challengi…
Resonant Magneto-phonon Emission by Supersonic Electrons in Ultra-high Mobility Two-dimensional System
Z. T. Wang, M. Hilke, N. Fong +4
We investigate resonant acoustic phonon scattering in the magneto-resistivity of an ultra-high mobility two-dimensional electron gas system subject to DC current in the temperature…
Interaction-Driven Asymmetry in the Breakdown of the = 1 Quantum Hall State
Hoai Anh Ho, Jian Huang, L. N. Pfeiffer +1
We report real-time detection of longitudinal and transverse transport responses across distinct frequency bands in a ferromagnetic filling factor = 1 integer quantum Hall sta…
Thermal Activation Signatures of the Anderson Insulator and the Wigner Solid forming near
S. A. Myers, Haoyun Huang, Waseem Hussain +3
When interactions overcome disorder, integer quantum Hall plateaus support topological phases with different bulk insulators. In the center of the plateau the bulk is an And…
