When a #negatively charged #electron is excited by #light, it leaves behind a positive hole. Because the hole and the electron are oppositely charged, they are attracted to each other and form a bond. The resulting pair, which is short lived, is known as an #exciton

Electrical control of hybrid exciton transport in a van der Waals heterostructure

EPFL engineers have found a way to control the interactions between excitons—quasiparticles that may one day transport data and replace the electrons in electronic devices. The engineers' method involves applying an electric field to a two-dimensional (2D) semiconducting material. Their findings appear in Nature Photonics.

Scientists find link between #photosynthesis and 'fifth state of matter' (#BoseEinsteinCondensate)

"#Photosynthetic light harvesting is taking place in a system that is at room temperature and what's more, its structure is disordered—very unlike the pristine crystallized #materials and cold temperatures that you use to make #exciton #condensates."

Scientists find link between photosynthesis and 'fifth state of matter'

Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Outside their window, trees gather sunlight and turn them into new leaves. The two seem unrelated—but a new study from the University of Chicago suggests that these processes aren't so different as they might appear on the surface.

“A University of Chicago study found links at the atomic level between photosynthesis and #exciton #condensates—a strange state of physics that allows energy to flow frictionlessly through a material. The finding is scientifically intriguing and may suggest new ways to think about designing electronics”
