Researchers at City College of New York physicist Vinod M. Menon's Laboratory for Nano and Micro Photonics (LaNMP) have ...

Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge ...

Last year, researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland developed a new type of transistor — one based on excitons, a special type of quasiparticle — which could ...

Bose-Einstein condensation (BEC) is normally limited to temperatures near absolute zero but researchers have now seen it at a much warmer 100 Kelvin for excitons (electron-hole pairs) in atomically ...

Two-dimensional perovskites are often seen as leading candidates for future LEDs and solar cells ...

Integrated optoelectronic devices, with electrons and photons as energy and information carriers, dominate current daily life and industrial development. However, electron- and photon-based devices ...

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are ...

If you read the scientific literature, you see the familiar subatomic particles you learned about in school: protons, neutrons, and electrons. If you are young enough, you see others you probably ...

How it happens: illustration of an antiferromagnetic CrSBr mirror-less cavity that allows the formation of exciton–polaritons. (Courtesy: Florian Dirnberger/City College of New York) An international ...

Things can always be done faster, but can anything beat light? Computing with light instead of electricity is seen as a breakthrough to boost the computer speeds. Transistors, the building blocks of ...

Single layers of transition metal dichalcogenides are two-dimensional (2D) direct-bandgap semiconductors with degenerate, but inequivalent, ‘valleys’ in the electronic structure that can be ...
