Superconducting germanium alloys have been known for decades, I used a Molybdenum/Germanium superconducting alloy in my PhD research 20 years ago, with much higher Tc.
The interesting aspect of this current experiment is the precise alignment of the Ga atoms into specific points of the Ge lattice, so preserving the crystalline structure order which leads to some interesting effects.
Really? First I've heard of it. And it also doesn't make any sense, since defintionally a material can't be superconducting and semiconducting at the same time, any more than it could be conducting and insulating at the same time. Are they imagining some new kind of thermal-switching circuitry?
This reads to me like the researchers came up with an irrelevant novelty (which is, to be fair, a valid and important part of scientific progress; it still expands our understanding of the universe) and Science Daily asked an LLM to rationalize it as useful.
