The development could improve power transistor performance, in turn creating more efficient power supplies for a range of applications.
“When I look at the future, I see that we can perhaps improve conductivity by an order of magnitude through optimising of the materials growth,” said University of Minnesota researcher Bharat Jalan. “We are bringing the possibility of high power, low energy oxide electronics closer to reality.”
Power transistors that use this combination of materials could lead to smaller devices and appliances because their power supplies would be more energy efficient and therefore run cooler.
“It’s fundamentally a different road toward power electronics,” said Sensale-Rodriguez, “and the results are very exciting. But we still need to do more research.”
