Abstract
The thermal resistance of layered semiconductor systems intended to be used for GaAs-based photomixing devices is studied. Layered systems with nonstoichiometric GaAs on the substrate exhibit an increase of thermal resistance of about 33%, while using a thin AlAs/GaAs multilayer structure leads to a thermal resistance only 10% larger than the thermal resistance of the GaAs substrate. The results are discussed with respect to the heat dissipation and implications for the photomixer device.
