Scientists at MIT and the City University of New York have imaged excitons’ motions directly for the first time.
A quasiparticle called an exciton — responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits — has been understood theoretically for decades. But exciton movement within materials had never been directly observed.
The finding could enable research leading to significant… read more
