Shifting away from silicon to large bandgap semiconductors could be a
way out. In principle such devices could operate at much higher
temperatures. The development push is coming from operation in hostile
environments, such as car engines and stand alone operations where
cooling is not available.
At this point I would guess that the best material would be silicon
carbide rather than gallium nitride. This is all pie in the sky right
now but there are no first principle obstacles just money and time.
