Which materials are superconductors at low temperatures?

Hundreds of materials are known to become superconducting at low temperatures. Twenty-seven of the chemical elements, all of them metals, are superconductors in their usual crystallographic forms at low temperatures and low (atmospheric) pressure.

Can a superconductor work at high temperatures?

Even as that paper was being retracted due to concerns about the validity of some of its data, Dias published a second paper claiming a similar breakthrough: a superconductor that works at high temperatures, but somewhat lower pressures. Shortly afterward, that got retracted as well.

What are the thermal properties of superconductors?

As stated above, the thermal properties of superconductors indicate that there is a gap in the distribution of energy levels available to the electrons, and so a finite amount of energy, designated as delta (Δ), must be supplied to an electron to excite it.
