From a team of City College of New York physicists and their collaborators in Japan and Germany comes another advancement in the study of excitons—electrically neutral quasiparticles that exist in insulators, semi-conductors and some liquids. The researchers have created an “excitonic” wire, or one-dimensional channel for excitons. This resulting devices could one day replace certain tasks that are now performed by standard transistor technology.
