Abstract


High density zinc oxide nanosheets arrays were grown on GaN-based light-emitting diodes at low temperature. It showed marked 20% increases in light output power at 20 mA of driving current compared to that of untreated LED. The enhancement of light output power is attributed to high density and surface-to-volume ratios of nanosheets as well as to enhanced multiple photons scattering at the nanosheets surface.
