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 ...

P-type semiconductors use dopants that act as electron acceptors. Boron fits into the crystal lattice just like silicon atoms, but since boron has only three electrons to use, a kind of hole is ...

Semiconductor quantum dots (QDs), consisting ... two recent papers show that an even better bet could be the absence of one electron (known as hole) or more precisely its spin 1,2.

The Korea Research Institute of Standards and Science (KRISS, President Ho Seong Lee) has successfully developed a high-quality compound semiconductor material for ultra-sensitive SWIR sensors.

The Korea Research Institute of Standards and Science has successfully developed a high-quality compound semiconductor material for ultra-sensitive short-wave infrared (SWIR) sensors. The study is ...

To improve the durability of tin perovskite, a method called Ruddlesden-Popper (RP) has been proposed that introduces large ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon ... Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an ...

This movement of electrons, and separation from their opposite-charged "holes," creates ... transfer across a semiconductor ...

Scientists have hypothesized that moiré excitons—electron-hole pairs confined in moiré ... may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits ...
