(a) Conventional InGaN/GaN MQW-based green LED structure on a flat sapphire substrate. (b) PS nanospheres in a monolayer form prepared on the Cr/SiO2/GaN substrate using a scooping transfer technique. (c) Triangularly patterned cylindrical nanorod arrays fabricated on the sapphire substrate. (d) Individually separated nanorod LEDs obtained by cutting the sample using a diamond knife. (e) Application of voltage for alignment of the individually separated nanorod LEDs between the interdigitated finger metal electrodes. (f) Nanorod LEDs aligned between the metal electrodes.
