So, I’ve been standing aloof from all this till more experiments had turned out.
This paper’s synthesis makes no sense, you can’t have any kind of uniforms strained lattice that way, so it would have to be a bulk characteristic superconductors which we’ve never seen before, ie resistance is low and on certain crystalline paths becomes fairly superconductive.
Maybe this is a random fluke and once they actually understand the Mechanics they can make a real superconductors through effective fabrication processes, but if anything this reminds me of Shockley’s first point-contact transistor in structure.
