Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged “hole,” moving together in a semiconductor. Created when an electron is excited to a higher energy state, excitons transfer energy without carrying a net charge. While their behavior in traditional semiconductors is well understood, excitons act differently in organic semiconductors.

Recent research led by condensed matter physicist Ivan Biaggio focuses on understanding the mechanisms behind exciton dynamics, quantum entanglement, and dissociation in organic molecular crystals.

The paper is published in the journal Physical Review Letters.
