A U of A engineering researcher is using sunlight and semiconductor catalysts to produce hydrogen by splitting apart water ...

Examples of such a dipole include an electron–hole pair in a semiconductor, which forms an exciton polariton, and the oscillating electrons at the surface of a metal, which creates a surface ...

A layered transistor design combines light detection optical memory and neuromorphic processing in one unit offering compact ...

Physicists have discovered that electronic excitations in 2D magnets can interact through spin waves – ripples in a ...

Scientists have discovered a new four-body quasi-particle, the quadruplon, in a 2D semiconductor. Using laser experiments and advanced theory, they identified unique spectral features unexplained by ...

Exciton delocalization is a mechanism of energy transfer between dyes, in which an exciton is a bound electron-electron hole pair created when a dye is excited by a photon of light. Delocalization ...

However, one major limitation of TiO₂ lies in the rapid recombination of photogenerated electron-hole pairs, which hampers its overall photocatalytic efficiency. To address this, researchers have ...

The researchers showed the emergence of interaction between electronic excitations (excitons—electron hole pairs) mediated via spin waves in atomically thin (2D) magnets. They demonstrated that ...

When exposed to sunlight, it functions like a microscopic power plant, generating energized electron-hole pairs that break down water molecules into hydrogen and oxygen, Liu explained. However ...

Chinese researchers recently achieved a breakthrough in "photocatalytic water splitting for hydrogen production." By performing "structural reshaping" and "element substitution" on a semiconductor ...
