Hybrid nanowires
Context
Superconductor-semiconductor core-shell nanowires are called hybrid nanowires. They form an exciting platform to study new phases of matter and to create novel quantum devices.In those structures, superconductivity is induced in the semiconductor nanowire by the proximity effect. The manipulation of this effect via multiple tuning knobs enables novel discoveries in materials science and in physics .
Our goal
We develop III-V nanowires by molecular beam epitaxy. The nanowires are grown from gold arrays designed by e-beam lithography.Superconducting shells are grown either in the same chamber or in an evaporator connected in-situ to the III-V chamber. We also send our samples to collaborators for superconducting deposition.
The nanowires are then studied for their structural, chemical and electronic properties.
