"A simple chemical surface treatment improves the performance of nanowire ultraviolet light-emitting diodes."
"A technique for reducing the loss of light at the surface of semiconductor nanostructures has been demonstrated by scientists at KAUST."
"Some materials can efficiently convert the electrons in an electrical current into light. These so-called semiconductors are used to create light-emitting diodes or LEDs: small, light, energy-efficient, long-lasting devices that are increasingly prevalent in both lighting and display applications."
"Postdoc Haiding Sun and his KAUST colleagues..., have developed LEDs that are made up of a tight array of dislocation-free nanometer-scale aluminum-gallium-nitride nanowires on a titanium-coated silicon substrate."
"Researchers reported that a simple passivation step using diluted potassium hydroxide was enough to offer a nearly 50% performance boost to UV LEDs at a wavelength of 338nm."
