Ubiquitous superconducting diode effect in superconductor thin films

Note: This is NOT about LK-99.

The APS summary is also helpful: https://physics.aps.org/articles/v16/122

Wow, getting an ideal diode in the real world would be huge for power conversion efficiency and cost. Currently you can get close with a semiconductor switch but there are still inefficiencies.

Can we get a superconductornews.ycombinator.com ?
