Quantum transport in hybrid nanostructures

In recent years a new material platform - a semiconductor nanostucture with a superconductor shell - has grown to become an important player in the field of electronic quantum transport. This, so-called hybrid material, embodies the characteristics of both constituent materials and is now widely used to study complex quantum phenomena. A particularly prosperous example of today is the semiconductor/Al nanowire. This work presents three experiments seeking to expand beyond the by-now established semiconductor/Al hybrid nanowires.

The experiments are, (1) low-temperature transport on InAs/Pb devices, (2) microtoming of InAsnanowires for scalable quantum devices and (3) a structural and electrical comparison of etched and shadowed junctions in InAs/Al nanowires.
