Chinese team reports quantum dot device that emits purer photon pairs
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, ...
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 ...
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 ...
Exciton and biexciton transient absorption spectra of CdSe quantum dots with varying diameters ...
We present a model to describe collective features of singlet fission in molecular crystals and analyze it using many-body theory. The model we develop allows excitonic states to delocalize over ...
(Nanowerk News) A rare spectroscopy technique performed at Swinburne University of Technology directly quantifies the energy required to bind two excitons together, providing for the first time a ...
