Flux trapping in NbTiN strips
Ruiheng Bai, Aliakbar Sepehri, Anne-Marie Valente-Feliciano +4
We use scanning superconducting quantum interference device (SQUID) microscopy to image individual vortices in superconducting strips fabricated from NbTiN thin films. By repeatedl…
Cascade of multi-electron bubble phases in monolayer graphene at high Landau level filling
Fangyuan Yang, Ruiheng Bai, Alexander A. Zibrov +6
The phase diagram of an interacting two-dimensional electron system in a high magnetic field is enriched by the varying form of the effective Coulomb interaction, which depends str…
Scaling NbTiN-based ac-powered Josephson digital to 400M devices/cm
Anna Herr, Quentin Herr, Steve Brebels +9
We describe a fabrication stackup for digital logic with 16 superconducting NbTiN layers, self-shunted a-silicon barrier Josephson Junctions (JJs), and low loss, high- tunable H…
Experimental determination of the energy per particle in partially filled Landau levels
Fangyuan Yang, Alexander A. Zibrov, Ruiheng Bai +4
We describe an experimental technique to measure the chemical potential, , in atomically thin layered materials with high sensitivity and in the static limit. We apply the techn…
