Is there a reason for 3 parts graphene, anyway? That's a lot. And I don't think averaging the thermoelectric sensitivities is how those work. They vary a lot with conditions and seem almost random from a table I looked at when trying to get one for molybdenum rhenium.
Honestly this is just a wild guess. I have no idea how thermoelectric works so I figured that suspending or just bracing the thermoelectric material with graphene would allow the thermoelectric material to tolerate higher stresses and temperatures. As such I honestly have no idea how realistic these are
Bump: will something like that work, and if yes - any obvious errors you see in them?
I do know that Gadofullerenes are of some interest due to promising use as MRI contrast, but as hot thermocouples?...
