Effect of thermal losses on the microscopic two-step heat conduction model

The effects of radiative and convective thermal losses on the thermal behavior of thin metal films, as described by the microscopic two-step heat conduction model, are investigated. It is found that radiative losses from the electron gas are significant in thin films having (L/Te3)<10−22, while radiative losses from the solid lattice are significant when (L/Te3)(Te4/Tl4)<10−22. Also, it is found that convective losses from the thin metal film are insignificant in most practical operating conditions.
