New quasiparticle unveiled in room temperature semiconductors

Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as the Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites.

Excitons will shape the future of electronic devices

Excitons are quasiparticles made from the excited state of electrons and—according to research being carried out EPFL—have the potential to boost the energy efficiency of our everyday devices.

Watching energy transport through biomimetic nanotubes

Scientists from the University of Groningen (the Netherlands) and the University of Würzburg (Germany) have investigated a simple biomimetic light-harvesting system using advanced spectroscopy combined with a microfluidic ...

New mechanism allows lower energy requirement for OLED displays

Scientists from RIKEN and the University of California San Diego, in collaboration with international partners have found a way to significantly reduce the amount of energy required by organic light emitting diodes (OLEDs). ...

Light from exotic particle states

A new type of light-emitting diode has been developed at TU Wien. Light is produced from the radiative decay of exciton complexes in layers of just a few atoms thickness.

Excitons pave the way to higher-performance electronics

After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.
