Patent 11756983 was granted and assigned to Massachusetts Institute of Technology on September, 2023 by the United States Patent and Trademark Office.
Light-emitting diodes having radiative recombination regions with deep sub-micron dimensions are described. The LEDs can be fabricated from indirect bandgap semiconductors and operated under forward bias conditions to produce intense light output from the indirect bandgap material. The light output per unit emission area can be over 500 W cm
