Abstract
A method is provided for preparing at least one textured layer in an optoelectronic device. The method includes epitaxially growing a semiconductor layer of the optoelectronic device over a growth substrate; exposing the semiconductor layer to an etching process to create the at least one textured surface on the semiconductor layer; and lifting the optoelectronic device from the growth substrate.
