Recently, the light output power of light-emitting duodes (LEDs) was enhanced due to the rapid development of epitaxy technique. As a result, a high internal quantum efficiency of around 90% has been achieved for AlGaInP LEDs. However, the ab

The authors propose a simple direct wet etching method to texture the indium-tin-oxide (ITO) p-contact layer of GaN-based light-emitting diodes (LEDs). It was found that high density ITO nanorods with average diameter of 140 nm and average height of

We propose a simple defect-selective wet etching method to form oblique sidewalls for GaN-based epitaxial layers with phosphoric acid. Using the same defect-selective wet etching, we also prepared GaN-based light-emitting diodes (LEDs) with undercut

Use of deep ultraviolet (248 nm) KrF laser irradiation to roughen vertical GaN-based LEDs surface with volcanolike protrusions for light output (Lop) improvement was proposed and demonstrated. After pulse irradiations of KrF laser (750-850 mJ/cm 2 ),
