Arya News - Researchers from St. Petersburg University found that semiconductors can cool themselves by converting heat into light.
The approach could help create compact lasers, photonic chips, and optical sensors where conventional cooling is too bulky or energy-intensive.

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.
