A new way to generate light through use of pre-existing defects in semiconductor materials

Researchers from the Low Energy Electronic Systems Interdisciplinary Research Group at Singapore-MIT Alliance for Research and Technology, MIT's research enterprise in Singapore, together with collaborators at the MIT, National University of Singapore and Nanyang Technological University have discovered a new method of generating long-wavelength (red, orange, and yellow) light through the use of intrinsic defects in semiconducting materials, with potential applications as direct light emitters i...
