Semi-Infinite Domain

Hello,
I have done a lot of research on how I can implement a semi-infinite domain, but I cannot seem to find an answer that is suitable for my specific application.
To simplify my problem, I have a microheater ontop of a thin section of Sb2S3. This microheater and section of Sb2S3 sit ontop of an infinitely wide and infinitely long section of SiO2. Underneath the SiO2 is an infinitely wide, infitely long and infitely thick Si substrate. This may be hard to picture so I have attached an image to illustrate this.
I want to apply a current across the microheater and monitor the temperature in the setion of Sb2S3. It is important that the layer of SiO2 and Si are large enough such that the heat does not build up in these domains thus affecting the temperature being measured. What is the best way to do this? I have tried using infinite domains but I am not sure how to control which direction they extend infinitely. I have also considered using a boundary condition but I am not sure how I would accurately model the conductive heat transfer.
I have attached the specific model I am working on as well. Any advice is greatly appreciated. Sincerely, Isaac
