Research

Covering the cutting edge global research in light based technologies.

When atomically thin layers of two materials are stacked and twisted, a heterostructure material emerges A new connection is formed, almost instantaneously, with special energy statesknown as interlayer excitonsthat exist in both layers

    Perovskite NIR LED with Record External Quantum Efficiency

    Researchers at Linköping University (LiU) in Sweden have produced near-infrared (NIR) light-emitting diodes (LED) of perovskite with a record external quantum efficiency of 21.6%. Because perovskites have good light-emitting properties and...

    Optical Tweezers Use Fluid Flow Instead of Light

    Researchers from the universities of Glasgow, Bristol and Exeter have collaborated to create an entirely new kind of optical tweezers that use fluid flow instead of light to control particles of any material and hold light-sensitive biological...
