New insights into the energy levels in quantum dots

Researchers from Basel, Bochum, and Copenhagen have gained new insights into the energy states of quantum dots. They are semiconductor nanostructures and promising building blocks for quantum communication. With their experiments, ...

A cavity leads to a strong interaction between light and matter

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This ...

Doubly-excited electrons reach new energy states

Positrons are short-lived subatomic particle with the same mass as electrons and a positive charge. They are used in medicine, e.g. in positron emission tomography (PET), a diagnostic imaging method for metabolic disorders. ...

Nanoplatelets improve LCD and LED screens

Researchers at the Physical and Analytical Chemistry department of the Universitat Jaume I (UJI) of CastellĂłn, Spain, have taken part in the design of semiconductor nanoplatelets with a broadened range of colours to improve ...
