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

KAUST researchers built beta-gallium-oxide transistors and logic devices that operate from near absolute zero to 500°C.

Silicon doping helped the devices keep conducting in extreme cold, while the ultrawide bandgap limited leakage at high heat.

The team demonstrated working FinFET and inverter circuits across the broad temperature range.

The results could reduce the need for heavy thermal management in harsh-environment electronics, including space missions and cryogenic computing.
