Enhanced Light Emitting Diodes

SUMMARY InGaN based quantum wells (QWs) light-emitting diodes and laser diodes play an important role in solids sate lighting (SSL). As the InGaN QWs are coupled to surface plasmon (SP) mode of metallic film, the radiative recombincation rate can be enhanced due to the increased photon density of states near the SP frequency. Lehigh University has...
