...But maybe thats even more interesting for, say, microelectronics? Especially if the resistance orthogonal to the superconductivity is high, if such a thing is even possible?
If you'd like to create one yourself, take a bunch of parallel insulated wires. Conductivity will be low along the wires, and high perpendicular to them.
Or alternated high-resistivity and low-resistivity sheets. Conduction will be low parallel to the sheets, and high going through them.
Lots of things behave like that.
The thinks you describes are systems made of multiple materials. Are you aware of a materials that behave that way by its own ?
A lot of materials (including any crystal) have a sense of direction.
As a simple example, consider graphite. That’s just ‘C’, but the crystalline version is layered, so it behaves differently depending on what direction you look at it.
Like wood, it will split easier when hammered parallel to the layers than when hit oblique to it.
Any Korean can give some brief summary over the book that tweets mentioned?
"The author writes on the influence and meaning of the certain future superconductor revolution on humanity, and while showing similar guise as Western science, he attempts to maintain the notion of the Oriental spirit, the confidence and self-esteem of East Asian scientist." Something like that. I'm not sure what it means.
(Also, yes, Choi Dongsik is probably correct.)
I mean, we're laundry list fantasizing, right? [shrug emoji]

"Origin of photovoltaic effect in superconducting YBa2Cu3O6.96 ceramics"
So theres the answer.
