It is known that the three metals with the highest conductivity, silver, copper and gold, do not experience superconductivity when cooled to cryotemperature at maximum.

I had this thought: What about the junctions that give the maximum, average and minimum Peltier effect? Moreover, it is necessary to cool deeply a certain jnction at a time when current flows through it, under normal conditions, a COOLING junction. Will such a junction experience a state of superconductivity, and if so, when?

It seems to me that at temperatures higher than the same state occurs in the individual metals of this junction, taken “individually”, not in a Peltier pair. And it is especially interesting what will happen to such pairs, in which one metal in a pair belongs to the three most electrically conductive, which do not experience “individually” superconductivity!

So, we take different Peltier pairs, pass a current in the direction of cooling and at the same time begin cooling them to cryotemperature in order to achieve a state of SUPERCONDUCTIVITY of the JUNCTION!

It would be interesting to “play” with gases that have “helium-like” atoms in structure. Maybe. during deep cooling, before they turn into a solid state, they also experience a state of superfluidity in a very narrow temperature range, usually unnoticeable, because they are closely “adjacent” to the “freezing” temperature!
