Next, they tackled the behavior of electrons. They discovered the concept of energy bands—the forbidden and allowed zones that determined whether a material was a conductor, insulator, or semiconductor. They learned about Fermi levels and how doping could tailor a material's electrical conductivity. spintronics | | Superconductivity | MRI
