Nice to see this area is still evolving, my PhD was in SiC-related tech, specifically how would you power a device embedded in a hostile environment so I was researching SiC-based photovoltaics, temperature response of piezoelectrics, high-temperature DC-DC converters and a very light touch effort on high-temperature storage. As soon as you start heating electronics up to these sorts of temperatures the things we already take for granted become problematic. As highlighted already, solder joints become a huge pain, wire bonds pop off, even just building the test rigs to test these devices is usually a pretty interesting problem - I built a high-temperature photovoltaic characterization rig and a high-temperature vibration rig, which was involved enough but the true monster was the gas-sensor characterisation lab which had evolved over many years that could do gas, high pressure and temperature up to 700 degC (I think). All good fun, if someone is looking at a PhD in electronics I would recommend this area if even vaguely interested as it's a good mix of practical and theory and when you can't even bank on your solder joints holding, let alone a dielectric surviving then it makes for some interesting problems away from the pure electronics.
