Few-electron Single and Double Quantum Dots in an InAs Two-Dimensional Electron Gas
Christopher Mittag, Jonne V. Koski, Matija Karalic +8
Most proof-of-principle experiments for spin qubits have been performed using GaAs-based quantum dots because of the excellent control they offer over tunneling barriers and the or…
Gate-defined Quantum Point Contact in an InSb Two-dimensional Electron Gas
Zijin Lei, Christian A. Lehner, Erik Cheah +5
We investigate an electrostatically defined quantum point contact in a high-mobility InSb two-dimensional electron gas. Well-defined conductance plateaus are observed, and the subb…
Relating Andreev Bound States and Supercurrents in Hybrid Josephson Junctions
F. Nichele, E. Portolés, A. Fornieri +8
We investigate superconducting quantum interference devices consisting of two highly transmissive Josephson junctions coupled by a superconducting loop, all defined in an epitaxial…
A Gate-Defined Quantum Point Contact in an InAs Two-Dimensional Electron Gas
Christopher Mittag, Matija Karalic, Zijin Lei +7
We experimentally study quantized conductance in an electrostatically defined constriction in a high-mobility InAs two-dimensional electron gas. A parallel magnetic field lifts the…
Wigner solid pinning modes tuned by fractional quantum Hall states of a nearby layer
A. T. Hatke, H. Deng, Yang Liu +5
We study a bilayer system hosting exotic many-body states of two-dimensional electron systems (2DESs) in close proximity but isolated from one another by a thin barrier. One 2DES h…
Wigner solids of wide quantum wells near Landau filling
A. T. Hatke, Yang Liu, L. W. Engel +4
Microwave spectroscopy within the Landau filling () range of the integer quantum Hall effect (IQHE) has revealed pinning mode resonances signifying Wigner solids (WSs) composed…
