CANCELLED: III-Nitride Nanorods as Building Blocks for Advanced Light Emitting Diodes

By Professor In-Hwan Lee

Department of Materials Science and Engineering, Korea University, Seoul, Korea

III-nitrides-based light emitting diodes (LEDs) are presently the leading solid state light sources for use in general lighting, displays, photodynamic therapy, water purification, etc.

This talk discusses the role of nanorod III-nitride LEDs, prepared by top-down dry etching, for improving the functionality, the crystalline quality, the internal quantum efficiency, and the light extraction efficiency.

The methods of nanorod fabrication, 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.
