The approach could help create compact lasers, photonic chips, and optical sensors where conventional cooling is too bulky or energy-intensive.

Russian Scientists Crack Chip Overheating With Quantum Trick
06:46 GMT 26.07.2026 (Updated: 07:58 GMT 26.07.2026) Researchers from St. Petersburg University found that semiconductors can cool themselves by converting heat into light.
Overheating is a perpetual headache in modern electronics. The more powerful the chip, laser, or optical sensor, the harder it is to dissipate excess heat
Scientists used a quantum well to trap electrons and holes, creating two exciton states at different energy levels
A laser excites one state; heat provides energy to jump higher, then a photon is emitted, cooling the material
The approach could help create compact lasers, photonic chips, and optical sensors where conventional cooling is too bulky or energy-intensive.
