Researchers Observe Evidence of Hyperbolic Exciton Polaritons

Researchers observe evidence of hyperbolic exciton polaritons

The ability to move electron-hole pairs—called excitons—in desired directions is important for generating electricity and creating fuels. This happens naturally in photosynthesis, making it a source of inspiration to researchers innovating optoelectronic devices.

NREL Team Observes Hyperbolic Exciton Polaritons In Novel Material.

Scientists observe hyperbolic exciton polaritons in a van der Waals magnet, opening new avenues for optoelectronic innovation. Professor Mark van Schilfgaarde at the National Renewable Energy Laboratory led a collaborative study demonstrating strong light-matter coupling in chromium sulfide bromide (CrSBr). This breakthrough addresses the challenge of controlling exciton movement and could enable the creation of novel devices inspired by photosy…
