Light extraction enhancement of GaN light-emitting diodes with ZnO micro-meshes pattern

Not Accessible

Your library or personal account may give you access

Abstract

To improve the light extraction of GaN light-emitting diodes, we fabricated ZnO micro-meshes pattern (MM) by photolithography and chemical deposition. ZnO MM can increase light output power by 42% attributed to light waveguide and diffraction-grating effect.
