Scientists achieve first direct observations of excitons in motion
Boston MA (SPX) Apr 17, 2014 - 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 has never been directly observed. Now scientists at MIT and the City College of New York have achieved that feat, imaging excitons' motions directly. This could ... more
