Scientists create electronic devices that function reliably at extreme temperatures from 500 degrees Celcuis to absolute zero — advanced semiconductor material unlocks new possibilities in space tech and quantum computing

Scientists at KAUST have developed electronic devices made of gallium oxide that can function reliably in extreme temperatures from near absolute zero to 500°C. These devices have potential applications in space tech and quantum computing due to their ability to withstand extreme temperature swings. By using ultrawide-bandgap semiconductor beta-gallium oxide and heavily doping it with silicon atoms, the researchers created devices that can maintain electrical conduction even in cryogenic conditions. The team built transistors and logic inverters that operated reliably at temperatures as low as 2K, paving the way for the development of temperature-resistant devices for various technological applications.
