Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicsts invented a method to 3-D-print these and other superconducting devices in minutes.

“Fabricating superconducting devices on a computer chip is a multi-step and demanding procedure, requiring dedicated facilities,” says Kaveh Lahabi, a physicist at Leiden Universty. “It usually takes days to complete,”

Lahabi and co-authors have developed a new approach, in which Josephson junctions, essential parts of SQUIDS, can be printed on almost any surface in mere minutes, within an electron microscope.

In this video, Lahabi and co-author Tycho Blom demonstrate their technique and discuss their recent article in ACS Nano.
