Voltage-tunable Josephson Junctions on Germanium Quantum Wells with in-situ Aluminum Contacts
Joshua P. Thompson, Jason T. Dong, Bernardo Langa +12
Voltage-tunable Josephson junctions (VT-JJs) are an emerging element in superconducting quantum electronics with potential to expand the functionality of conventional designs. Whil…
An evaluation of A15 Nb3Al superconducting thin films for application in quantum circuits
Joseph Falvo, Brooke Henry, Bernardo Langa +4
A15 superconductors are distinguished by their high critical temperatures, magnetic fields, and current-carrying capabilities. Among them, NbAl is of particular interest for su…
Spin-orbit coupling in digital alloyed InGaAs quantum wells
Jason T. Dong, Yilmaz Gul, Irene Villar Rodriguez +5
Increasing the spin-orbit coupling in InGaAs quantum wells is desirable for applications involving spintronics and topological quantum computing. Digital alloying is an approach to…
Missing odd-order Shapiro steps do not uniquely indicate fractional Josephson effect
P. Zhang, S. Mudi, M. Pendharkar +10
Topological superconductivity is expected to spur Majorana zero modes -- exotic states that are also considered a quantum technology asset. Fractional Josephson effect is their man…
Near-half-metallic state in the half Heusler PtMnSb film on a III-V substrate
Shinichi Nishihaya, Malcolm J. A. Jardine, Hadass S. Inbar +9
The interplay between half-metallic ferromagnetism and spin-orbit coupling within the inversion symmetry-broken structure of half Heuslers provides an ideal platform for various sp…
