Why don't room temperature superconductors exist?

Entropy. At room temperature and atmospheric pressure the structure of any material is too noisy. Spins flipping every now and then, atoms vibrating. The current high temperature superconductor works ...

Why don't room temperature superconductors exist?

Different materials have different limitations. Sometimes spins of charge-carriers are not paired strongly enough, sometimes all the paired electrons form localized covalent bonds. To form a stable ...

Why don't room temperature superconductors exist?

(My answer is a bit off-topic to the theoretical "why" answered well by others, but I believe the particular wording of OP's post is evocative of a relatively common misunderstanding of the ...

Why don't room temperature superconductors exist?

The honest answer is we don't know As DrMoishe Pippik points out in their answer we have a good theoretical explanation of superconductivity only for one class of superconductors. And that Nobel Prize ...

Why don't room temperature superconductors exist?

For classical superconductivity, the Bardeen–Cooper–Schrieffer (BCS) theory states electrons travel in Cooper pairs. Since, at the quantum level, it is hard to distinguish one electron from the other, ...

Why is fullerene 60 an insulator while graphite is a conductor?

The answer lies apparently in the symmetry of the molecule. Have a look at this explanation. (However, I found this question because I wanted more info, since I am not comfortable with all the ...
