New imaging method offers fresh insight into LED materials

Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. A new study involving researchers from the University of Liverpool and the University of Strathclyde has demonstrated a powerful way to identify tiny crystal defects that can reduce the efficiency of LED materials. The advance could help scientists better understand how these defects form and ultimately support the development of more efficient electronic and optoelectronic devices.
