Recent observations of missing odd Shapiro steps have been interpreted in the context of topological superconductivity. Here, the authors observe missing odd Shapiro steps in topologically trivial Josephson junctions due to high transparency of the j

The anomalous Josephson effect can be regarded as the hall-mark effect of superconducting spintronics. Here, the authors report the observation of a tunable anomalous Josephson effect in InAs/Al Josephson junctions measured via a superconducting quan

We report a probable observation of the dc Josephson effect in mesoscopic junctions of three and four superconductors. The devices are fabricated in a top-down fashion from a hybrid semiconductor-superconductor InAs/Al epitaxial heterostructure. In g

We fabricate Josephson junction field-effect transistors (JJ-FETs) using InAs quantum well heterostructure as the channel, epitaxial Al as superconducting electrodes, and scaled-down Al2O3 gate dielectrics. A systematic investigation of the gate volt

The proliferation of van der Waals (vdW) heterostructures formed by stacking layered materials can accelerate scientific and technological advances. Here, we report a strategy for constructing vdW heterostructures through the interface engineering of

Near surface indium arsenide quantum wells have recently attracted a great deal of interest since they can be interfaced epitaxially with superconducting films and have proven to be a robust platform for exploring mesoscopic and topological supercond

Josephson junctions hosting Majorana fermions have been predicted to exhibit a 4π periodic current phase relation. One experimental consequence of this periodicity is the disappearance of odd steps in Shapiro steps experiments. Experimentally, missi
