How does diamond conduct heat?
Diamond is a cubic crystal structure, where each carbon atom is covalently bonded with four other carbon atoms in SP3 hybridized orbitals, constituting an orthotetrahedron. Because all valence electrons are confined to the covalent bond region, and there are no free electrons, diamond is not electrically conductive. High thermal conductivity is associated with high electrical conductivity. Unlike metals, which rely on peripheral electrons for heat transfer, diamond's thermal conductivity is essentially derived from the propagation of vibrations of carbon atoms (i.e., phonons).
