 Conventional superconductor

Conventional superconductors are materials that exhibit superconductivity primarily due to the Bardeen-Cooper-Schrieffer (BCS) theory, which explains the phenomenon in terms of electron pairs known as Cooper pairs. Here are some key features of conventional superconductors: 1. **BCS Theory**: Conventional superconductivity arises from the formation of Cooper pairs, where two electrons with opposite spins and momenta pair up due to an attractive interaction mediated by lattice vibrations or phonons.
