Photoacoustic study of the effect of aluminum content on the thermal and thermomechanical properties of on GaAs in the range

Abstract:

The two layer system on GaAs is studied in the range The open photoacoustic cell technique is used to obtain thermal diffusivity, thermal conductivity, heat capacity, and the thermal expansion coefficient. It is shown that the thermal properties of the individual layers can be determined using the low modulation frequency regime models without actually separating the two layer system. The possibilities and advantages of the approach for the thermal characterization of layered semiconductor systems are discussed.
