Nanowire could provide a stable, easy-to-make superconducting transistor
Superconductors—materials that conduct electricity without resistance—are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They're found in medical imaging, quantum computers, and cameras used with telescopes.
But superconducting devices can be finicky. Often, they're expensive to manufacture and prone to err from environmental noise. That could change, thanks to research from Karl Berggren's group in the Department of Electrical Engineering and Computer Science.
The researchers are developing a superconducting nanowire, which could enable more efficient superconducting electronics. The nanowire's potential benefits derive from its simplicity, says Berggren. "At the end of the day, it's just a wire."
Berggren will present a summary of the research at this month's IEEE Solid-state Circuits Conference.
