title = "Enhancement of extraction efficiency in laser-debonded GaN light emitting diodes",
abstract = "We conducted detailed investigations of laser-assisted debonding of GaN-based light emitting diodes (LEDs). The devices were grown by metalorganic chemical vapor deposition (MOCVD) on sapphire substrates. After laser debonding the devices were photoelectrochemically (PEC) etched for the roughening of the debonded surface. The dependence of the luminous intensity of the LEDs as a function of the surface roughness was investigated in detailed. A 60% increase in the luminous intensity was observed. This increase is attributed to the enhancement in photon extraction efficiency.",
