Russian Scientists Crack Chip Overheating with Quantum Trick
NTI Center for Quantum Communications, NUST MISiS
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 heatScientists used a quantum well to trap electrons and holes, creating two exciton states at different energy levelsA laser excites one state; heat provides energy to jump higher, then a photon is emitted, cooling the materialThe approach could help create compact lasers, photonic chips, and optical sensors where conventional cooling is too bulky or energy-intensive.
