i think the peltier effect using the n and p type already available
would make a suitable heat pump from the hot zones!!

cheers

Peltier effect is a horrible way to remove heat. It generates about
twice as much heat as it moves so that for every Watt you want to
extract, you have to then get rid of 3 Watts!

It is useful on larger scales when you want to move heat and don't have
the space to use anything that might actually be somewhat efficent.

as i understand it depends on a high work function ( i.e germanium
better) and not using large swaths of high resistance n or p, but
metal. in this way the transit distance can be increased without a
major power loss.

if the lines are carrying power anyhow, an occasional insert of in
metal runs of p or n type would conduct heat away.

other than that the hall effect could be used to keep low energy
electrons on a capacitor heat sink, and the high energy ones could be
conducted away?!!

I think i just invented the coolasitor
