Journal ArticleDOI
Highly efficient GaN-based high-power flip-chip light-emitting diodes
TL;DR: It is shown that it is possible to improve both the light extraction efficiency (LEE) and current spreading of an FCLED by incorporating a highly reflective metallic reflector made from silver (Ag), which paves the way towards higher-performance LED technology.
Journal ArticleDOI
