A rare spectroscopy technique directly quantifies the energy required to bind two excitons together. The experiment harnessed interactions between real and virtual states to 'switch' the electronic ...

Due to the size-dependent quantum confinement effects, quantum dots (QDs) exhibit excitonic properties with tunable absorption and emission properties for modern photonics. Efficient single photon and ...

When the carrier density is increased in a semiconductor, according to the predictions of Sir Nevil Mott, a transition should occur from an insulating state consisting of a gas of excitons to a ...

A research team in China has built a quantum dot device that produces photon pairs with record-setting purity, achieving a two-photon fraction of 0.983(1). The work, published in Nature Materials, ...

New research increases our understanding of how light interacts with atomically thin semiconductors and creates unique excitonic complex particles, multiple electrons, and holes strongly bound ...
