Abstract:
1. A method for making a light-emitting device capable of emitting a light having a wavelength ranging from 300 to 550 nm, comprising: (a) forming a multilayered structure on a first substrate, the multilayered structure including a n-type semiconductor layer disposed on the first substrate, an active layer disposed on the n-type semiconductor layer, and a p-type semiconductor layer disposed on the active layer; (b) attaching the multilayered structure to a second substrate and removing the first substrate from the multilayered structure to expose the n-type semiconductor layer; (c) depositing particles on the n-type semiconductor layer as an etching mask; and (d) etching an exposed portion of the n-type semiconductor layer peripheral to the particles to form a portion of the n-type semiconductor layer as a waveguide structure, the waveguide structure including a plurality of spaced apart nanorods extending from the n-type semiconductor layer.
