“HYPERSONIC phononic crystals could also have a large impact in thermal management. Thermal energy in solids is transported primarily by electrons and phonons. The electronic contribution is important for materials with a large number of free carriers, such as metals. The presence of a phononic band gap would reduce the flow of phonons and therefore the thermal conductivity of a solid.”
