Why Metals Are Not Good Superconductors?
Why Metals Are Not Good Superconductors? In pure elemental metals, the attractive force between electrons is mediated by phonons (lattice vibrations), so you need a rather strong electron-phonon (E-P) interaction to get the Cooper pairs to form. … So el-phonon interaction is not pronounced….so they are bad superconductor. Why a good metal can never be
