There are several other phenomena in superconductors for which BCS theory provides no explanation. Furthermore, BCS theory has proven unable to predict any new superconducting … Nettetpeared. This is exactly the selfconsistent equation obtained by BCS theory. As a result T c and Δ are not affected by the presence of disorder. This is an extremely powerful and important result. As such, it is important to remember under what conditions it is valid. Our derivation was quite general, but relied on one key as sumption.
