Title
Enhancement of GaN-Based Light-Emitting Diodes Transferred From Si (111) Substrate Onto Electroplating Cu Submount With TiO
/SiO

 light-emitting diodes (LEDs) were transferred from Si (111) substrate onto the electroplating Cu submount, with inserting a 5-pair TiO<sub>2</sub>/SiO<sub>2</sub> omnidirectional reflector (ODR) and an Al mirror, defined as TiO<sub>2</sub>/SiO<sub>2</sub>-Al ODR. The reflectivity in the blue spectral range of the TiO<sub>2</sub>/SiO<sub>2</sub>-Al ODR was as high as 97%. The current-voltage (I-V) characteristics showed no obvious degradation of electrical properties for the ODR-based LED on Cu. In comparison to conventional LEDs on Si without ODRs, the light output of ODR-based LEDs on Cu was enhanced by 59.3% at a driving current of 350 mA. The improvement is mainly attributed to the following factors: the removal of the opaque Si substrate, the inserting of the high-reflectivity TiO<sub>2</sub>/SiO<sub>2</sub>-Al ODR, and the transfer onto the Cu submount with better thermal conductivity.</div></div>
