This article presents a discussion on the role of nanowire (NW) structures, prepared by reactive ion etching (RIE), in planar III-nitride light emitting diodes (LEDs) for increasing the functionality, improving the crystalline quality, enhancing the quantum efficiency of radiative recombination, and improving the light extraction efficiency. The methods of NW fabrication by RIE, of suppressing the adverse effects of RIE-related damage, and of incorporating air voids into the NWs are also discussed. Furthermore, metal nanoparticles producing localized surface plasmons and semiconductor quantum dots downconverting the wavelength of light emitted by LEDs are explored.

In-Hwan Lee received his PhD degree in Materials Science and Engineering in 1997 from Korea University in South Korea. During 1997–1999, he was a postdoctoral fellow at Northwestern University. Then, he joined Samsung Advanced Institute of Technology, where he led an epitaxial team and developed InGaN/GaN violet laser diodes. From 2002 to 2017, he was a professor in Division of Advanced Materials Engineering at Chonbuk National University in South Korea. With the sabbatical grant from LG foundation, he was at Yale University during 2008– 2009. In March 2017, he joined Department of Materials Engineering, Korea University, Korea as a full professor. His current research focuses on the development of nanotechnology-inspired novel optoelectronic devices including light-emitting diodes, photovoltaic devices, and sensors.
