Heat diffusion is studied in the two-layer GaAs/GaSb system, produced by the union of wafers by means of the fusion technique. Analysis of the thermal diffusivity of these systems demonstrates the role that the union plays in heat transport in these systems as a function of the temperature used in the joining process. The thermal diffusivity measurements were carried out by means of the photoacoustic technique in a heat transmission configuration.
