Scientists from MIT and elsewhere studied gallium nitride's properties and performance at extremely high temperatures.
They found that extreme temperatures didn't cause significant degradation to the material or contacts.
They were surprised to see that the contacts remained structurally intact even when held at 500C for 48 hours .
Understanding how contacts perform at extreme temperatures is an important step toward developing high-performance transistors that could operate on Venus .
Contact resistance seems to remain constant even at temperatures of 500C.
Researchers plan to use what they learned in these experiments to develop high-temperature gallium nitride transistors.
The material did start to degrade after being in the furnace for 48 hours , but the researchers are already working to boost long-term performance.
