Quantum capacitance anomalies of two-dimensional non-equilibrium states under microwave irradiation
Jian Mi, Jianli Wang, Saeed Fallahi +3
We report our direct study of the compressibility on ultrahigh mobility two-dimensional electron system ( cm/Vs) in GaAs/AlGaAs quantum wells unde…
Electron-Hole Asymmetric Chiral Breakdown of Reentrant Quantum Hall States
Alexander V. Rossokhaty, Yuval Baum, Joshua A. Folk +3
Reentrant integer quantum Hall (RIQH) states are believed to be correlated electron solid phases, though their microscopic description remains unclear. As bias current increases, l…
High-fidelity entangling gate for double-quantum-dot spin qubits
John M. Nichol, Lucas A. Orona, Shannon P. Harvey +4
Electron spins in semiconductors are promising qubits because their long coherence times enable nearly 10^9 coherent quantum gate operations. However, developing a scalable high-fi…
Evidence for a new symmetry breaking mechanism reorienting quantum Hall nematics
Q. Shi, M. A. Zudov, J. D. Watson +2
We report on the effect of in-plane magnetic field on stripe phases in higher () Landau levels of a high-mobility 2D electron gas. In accord with previous stud…
Reorientation of quantum Hall stripes within a partially filled Landau level
Q. Shi, M. A. Zudov, J. D. Watson +2
We investigate the effect of the filling factor on transport anisotropies, known as stripes, in high Landau levels of a two-dimensional electron gas. We find that at certain in-pla…
Modified MBE hardware and techniques and role of gallium purity for attainment of two dimensional electron gas mobility >35 x10^6 cm^2/Vs in AlGaAs/GaAs quantum wells grown by MBE
Geoffrey C. Gardner, Saeed Fallahi, John D. Watson +1
We provide evidence that gallium purity is the primary impediment to attainment of ultra-high mobility in a two-dimensional electron gas (2DEG) in AlGaAs/GaAs heterostructures grow…
