Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
Planar Josephson junction devices with narrow superconducting strips: Topological properties and optimization
Purna P. Paudel, Javad Shabani, Tudor D. Stanescu
We study the low-energy physics of planar Josephson junction structures realized in a quasi-two dimensional semiconductor system proximity-coupled to narrow superconducting films.…
Microwave-Tunable Diode Effect in Asymmetric SQUIDs with Topological Josephson Junctions
Joseph J. Cuozzo, Wei Pan, Javad Shabani +1
In superconducting systems in which inversion and time-reversal symmetry are simultaneously broken the critical current for positive and negative current bias can be different. For…
Dynamical vortex transitions in a gate-tunable Josephson junction array
C. G. L. Bøttcher, F. Nichele, J. Shabani +2
We explore vortex dynamics in a two-dimensional Josephson junction array of micron-size superconducting islands fabricated from an epitaxial Al/InAs superconductor-semiconductor he…
The study of contact properties in edge-contacted graphene-aluminum Josephson junctions
Zhujun Huang, Neda Lotfizadeh, Bassel H. Elfeky +8
Transparent contact interfaces in superconductor-graphene hybrid systems are critical for realizing superconducting quantum applications. Here, we examine the effect of the edge-co…
Coexistence of superconductivity and weak anti-localization at KTaO3 (111) interfaces
Athby H. Al-Tawhid, Jesse Kanter, Mehdi Hatefipour +3
The intersection of two-dimensional superconductivity and topologically nontrivial states hosts a wide range of quantum phenomena, including Majorana fermions. Coexistence of topol…
Detecting induced pairing at the Al-InAs interface with a quantum microwave circuit
D. Phan, J. Senior, A. Ghazaryan +5
Superconductor-semiconductor hybrid devices are at the heart of several proposed approaches to quantum information processing, but their basic properties remain to be understood. W…
Tailoring Superconducting Phases Observed in Hyperdoped Si:Ga for Cryogenic Circuit Applications
K. Sardashti, T. Nguyen, M. Hatefipour +5
Hyperdoping with gallium (Ga) has been established as a route to observe superconductivity in silicon (Si). The relatively large critical temperatures (T) and magnetic fi…
Electrical control of Majorana Bound States Using Magnetic Stripes
Narayan Mohanta, Tong Zhou, Junwen Xu +5
A hybrid semiconductor-superconductor nanowire on the top of a magnetic film in the stripe phase experiences a magnetic texture from the underlying fringing fields. The Zeeman inte…
The multi-terminal Josephson effect
Natalia Pankratova, Hanho Lee, Roman Kuzmin +6
Establishment of phase-coherence and a non-dissipative (super)current between two weakly coupled superconductors, known as the Josephson effect, plays a foundational role in basic…
