Structured LED devices and component structures with improved efficiency and reduced defects are enabled by the use of micro- or nano-structured features that reduce lattice strain and improve p-doping in inorganic LEDs, and facilitate carrier injection and recombination of OLEDs. The nanostructures can also confine current flow and provide internal light guiding to enhance efficiency and thereby improve device performance.
