Quantum Transport in Nanowires Grown via Template Assisted Selective Epitaxy and Contacted by an s-wave Superconductor

The hybrid system of an s-wave superconductor and a semiconducting nanowire with strong spin-orbit coupling (e.g. InAs, InSb) is a robust platform for realizing Majorana Fermion, a quasi-particle which is considered to be the building block for fault tolerant quantum computation. In our study, we prepare InAs nanowire networks using Template Assisted Selective Epitaxy (TASE) method and contact them using an s-wave superconducting material. The TASE method offers a reproducible way to grow high-quality nanowire in non-trivial device geometries, such as cross and Y- junctions, proposed for braiding operations of Majorana Fermions. Here, we present the quantum transport data measured on TASE-grown InAs nanowires with different device geometries.
