Although you can induce superconductivity by changing the atomic structure with increased pressure, the big secret to this electron magic trick is temperature. Because temperature is essentially just energy by another name, it brings with it thermal excitations that disrupt these paired electrons, Mason says. So for a material to be a superconductor, that thermal energy must be lower than the paired electrons’ energy. That’s why superconductors usually occur at temperatures approaching absolute zero, when such thermal energy is extremely low.
Emphasis on the word “usually.”
