SPECIFIC HEAT AT THE NANOSCALE
Specific heat is thought to be an intensive thermophysical property of a material independent of the dimensions of the body. Today, specific heat at the nanoscale is assumed the same as that of macroscopic bodies. In effect, the classical equipartition theorem is assumed valid allowing the atom to have thermal energy at all wavelengths. But quantum mechanics does not allow the atom to have the heat capacity at the submicron wavelengths necessary to store thermal energy in nanostructures, the consequence of which is absorbed energy cannot be conserved by an increase in temperature. Conservation may only proceed by the quantum electrodynamics induced frequency up-conversion of absorbed energy by non-thermal electromagnetic radiation that leaks to the surroundings. Specific heat at the nanoscale is therefore not an intensive property of a material, but rather an extensive property depending on the body dimensions.
