New model of heat transport across the metal-insulator interface by the example of boundaries in a diamond-copper composite

A model of heat transport from an insulator (diamond) to a metal (copper) has been proposed taking into account energy transport to the oscillations inherent in the insulator but having frequencies much higher than the frequencies inherent in the fundamental oscillations of the metal. This problem is solved exactly in the one-dimensional case and in the one-constant approximation of bonding at the interface. It has been established that energy transport occurs in a thin layer near the metal boundary.
