@JCat I wasn't speaking of normal current shunt monitoring that most mods use to calculate resistance.
There is a pretty common and simple electronics trick in that you can use any diode (semiconductor) in a circuit as a temperature sensor as long as you know the bias, it is pretty common to use in-die on CPUs. I have used the Texas Instruments lm 95235 in a design before which called for something similar.
The picture posted with the gold contacts just brings to mind some Schottky diodes we looked at not too long ago for a customer who needed a high power application, some of the newer Diodes are basically Silicon Carbide with vacuum deposited gold layers.
Anyways, I am rambling...
Interesting. The problem I'd anticipate with using the semiconductor properties of SiC as a diode and then using the forward voltage drop change as a temp sensor is that SiC diodes are only good to somewhat under 200°c. And resulting clamp voltage would make any mode, power or tc, a problem for any mod. Or so my modeling leads me to believe. All speculation, at this point tho.
