Superconductivity

yes

Nobody knows if it is possible or impossible to fabricate room temperature superconducting material. There are many brilliant minds doing fundamental research on that very topic right now. But none of them know if this is ultimately possible or not. That's why it is called research.

You've stumbled onto one of the pivotal attributes that seems to be required for superconductivity to happen. The lattice structure of the atoms must be very rigid. The electron and hole propagation (current) then imparts no energy into vibrations of the mass of the atomic nuclei. This self heating phenomena is the fundamental of resistance. Higher temperatures in a solid state material are the very antithesis of a rigid lattice structure. That's a very, very loose description of the very complicated topic of the solid state theory of supeconduction.

I mean there must be some limits. Superconductivity exist in the premise of the 3rd Law of Thermodynamics, that is freezing all subatomic activities or processes at subzero. That means a material at that temperature behaves fluid like space. Entropy increases with temperature. Entropy production approaches to zero as absolute zero temperature is reached. Above zero temperatures say room temp. it is interesting to know how will they be able to make the atomic activity like that at zero temperature. would that be even possible?

You didn't Google first did you?

Everything you have ever asked about is available by using a little of your own energy.

Do some homework before asking to forum to educate you!

The good news is that superconductivity is not completely understood. We thought we understood it (BCS theory) which limited the temperature to about 30 K until 1986 when a new class of superconductors were discovered. So the door's wide open. There's a Nobel Prize out the with someone's name on it.
