Heat diffusion in the two layer system GaAs/GaSb joined by the fusion technique

Heat difusion is study in the two layer GaAs/GaSb system. Analysis of the thermal diffusivity of these systems demostrates the rol that the union plays in heat transport in these systems as a function of the temperature used in the joining process. The termal diffusivity measurementswere carried out by mean of the photoacoustic technique in a heat transmission configuration.
