In this thesis, three dimensional superconducting arches were fabricated using this technique with the help of a computer aided design (CAD) program. Magnetic field sweeps were performed at low temperatures (∼2-5 K) to characterize these arches. With a few improvements, more complex 3D structures can be fabricated, paving the way towards the numerous applications people now can only dream of.Show less

Conventional fabrication methods revolve around a multi-step lithography process that encompasses etching, heating, chemical cleansing and coating, thereby limiting these techniques in practice. In this thesis we present a non-destructive alternative approach that does not entail pre- or post processing, namely, a direct-write printed SQUID patterned under 20 minutes using Focus Electron Beam Induced Deposition (FEBID). The Josephson behaviour of these devices is confirmed by performing out-of-plane magnetic field sweeps and measuring the corresponding oscillations in critical current. Our endeavours pave the way for printing sophisticated quantum systems and three dimensional superconducting sensors.Show less
