The authors applied a simple, low-cost, mass-producible contact-transferred and mask-embedded lithography (CMEL) to texture p-GaP window layer for the fabrication of InGaAlP light-emitting diodes (LEDs) emitting at 612 nm. Under 20 mA current injection, it was found that forward voltages were 2.25, 2.24 and 2.25 V for CMEL-400 nm LED, CMEL-2 μm LED and the conventional LED without CMEL, respectively. It was also found that the 20 mA output powers were 1.43, 1.28 and 1.16 mW for CMEL-400 nm LED, CMEL-2 μm LED and the conventional LED without CMEL, respectively.
