Abstract
The present disclosure provides a light emitting diode and a method of manufacturing the same. The light emitting diode includes a graphene layer on a second conductive semiconductor layer and a plurality of metal nanoparticles formed on some region of the graphene layer, whereby adhesion between the second conductive semiconductor layer comprised of an inorganic material and the graphene layer is enhanced, thereby securing stability and reliability of the light emitting diode. In addition, the light emitting diode allows uniform spreading of electric current, thereby allowing stable emission of light through a surface area of the light emitting diode. The method of manufacturing a light emitting diode includes forming a graphene layer on a second conductive semiconductor layer, forming a mask film on the graphene layer, forming a metal layer within the patterns of the mask film, followed by removing the mask film; and heat treating the metal layer to form a plurality of metal nanoparticles, whereby the metal nanoparticles having a high index of refraction are formed on some region of the graphene layer and provide surface texturing effects, thereby improving light emission efficiency.
