The Density of States diagram gives gaps sometime. As I know, if the band is filled up to the gap, then the material is an insulator.(adsbygoogle = window.adsbygoogle || []).push({});

However, it seems to me, that superconductors also open a gap in their density of states diagram, as BCS theory says.

If my understanding is correct, I am a little confused here, so how can you tell the difference between an insulator and an superconductor?

Thanks a lot for whom could give me some help
