Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made significant progress in photocatalysis by unveiling a "super" photoreductant ...

Colloidal quantum dots for optoelectronics Colloidal quantum dots are nanometre-sized semiconductors with unique, size-dependent, optoelectronic properties owing to quantum confinement.

The researchers deployed a special quantum effect called the two-photon spin-exchange Auger process to produce hot electrons far more efficiently than before. This process allows two low-energy ...
