AbstractWe report experimental investigation of laser-assisted debonding of GaN-based light emitting diodes (LEDs) grown by metalorganic chemical vapor deposition (MOCVD) on sapphire substrates. The device was photo-electrochemically (PEC) etched to form hexagonal pyramid hillocks on the debonded surface. The luminous intensity of the debonded and roughened LEDs increased by 60% when compared to the LEDs on sapphire. This increase is attributed to the enhancement in photon extraction efficiency.
