Recent years superconductor-semiconductor hybrid materials have been established as an essential platform for quantum devices, notably used in the search for Majorana zero modes and other bound states that may serve as qubits. In this talk we will look beneath the surface of these nanowire devices and discuss recent advances in materials science and nanofabrication. In particular we will see how in-situ fabrication and new superconductors have been implemented, expanding the available parameter space for hybrid quantum devices.
