When isolated atoms come together to form a solid, their discrete energy levels split and merge into continuous energy bands: Electrons move freely
The valence and conduction bands overlap, or the valence band is only partially full. Electrons move freely. Insulators: A large band gap (typically ) prevents electrons from jumping to the conduction band. Semiconductors: A small band gap (typically
Phonons are the primary mechanism for heat conduction in insulators. In metals, free electrons dominate heat transport.
