What is the best way to bond GaAs to the intrinsic layer of a laser diode? I am planning on building a refactory oven on a concrete pad this summer once I clear of one side of my yard. There is just no way around it, everything I want to do involves super high heat whether its melting glass in a platinum coated mold for optics or bonding GaAs, etc.
But what is the best way of accomplishing this, it seems the oven is the same its just whether you allow multiple holes to connect a vacuum pump or have a rotating tray or the ability to hang the substrate upside down, etc.
Magnetron sputtering is probably the easiest and I already have all the parts for it I just need more indoor work space.
I found this super high heat cement that can be poured into what ever shape I want and then just layer the bottom in fire brick to protect the concrete pad as much as possible - https://www.sheffield-pottery.com/LO...AR-p/lvclc.htm
And these heating elements which seem to be a good deal and would allow for close temperature control by regulating current - https://molybdenum-cn.en.made-in-chi...t-Furnace.html
Do they have special valves that are super thermal insulators to keep tons of heat from escaping from the vacuum ports? If I can just sputter the GaAs right onto the substrate that would be great but typically the GaAs IS the substrate ...
