Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Excitons, quasiparticles formed by an electron and a hole, transfer energy without a net charge. Physicist Ivan Biaggio ...

Scientists have unlocked the secret world of dark excitons — tiny energy carriers crucial for the future of solar power and ...

How can the latest technology, such as solar cells, be improved? An international research team led by the University of ...

The metal–semiconductor junction in Schottky barrier devices has the crucial role of establishing a built-in potential, and a field to separate electron–hole pairs. In light of the sub-optimal ...

How can the latest technology, such as solar cells, be improved? An international research team is helping to find answers to questions like this with a new technique. For the first time, the ...

When light strikes quantum dots in the device ... Water molecules not only help separate the initial electron-hole pairs but also form organized channels that help transport these charges. The quantum ...

Dark excitons are tiny pairs consisting of an electron and the hole left behind when it becomes excited. They carry energy but do not emit light, giving them the name “dark.” An exciton can be ...

Boron fits into the crystal lattice just like silicon atoms, but since boron has only three electrons to use, a kind of hole is created where an electron ... high-intensity light in a process ...
