The large amount of light emitted from a light emitting diode (LED) being trapped inside the
semiconductor structure is the consequence of the large value of the refractive index. The …

Colloidal crystals (CCs) are ordered arrays of monodisperse colloidal particles. Because of
the presence of a periodic superlattice of colloids and voids, CCs bear many unique …

Light management is of paramount importance to improve the performance of optoelectronic
devices including photodetectors, solar cells, and light-emitting diodes. Extensive studies …

Defective silica sphere arrays having locally hexagonal‐closed‐packed structure but lack of
long range ordering were incorporated into organic light emitting diodes as grating to extract …

The fabrication studies of silica/polystyrene (PS) colloidal microlens arrays with various
aspect ratios were performed on the III-nitride light-emitting diodes (LEDs). The use of …

Materials exhibiting multidimensional structure with characteristic lengths ranging from the
nanometer to the micrometer scale have extraordinary potential for emerging optical …

Convective deposition of a monolayer of microspheres by drawing a meniscus of a
suspension across a substrate is used to fabricate microlens arrays to enhance the photon …

The progress in III-Nitride photonics research in 2009 is reviewed. The III-Nitride photonics
research is a very active field with many important applications in the areas of energy …

Three-layer staggered InGaN quantum wells (QWs) light-emitting diodes (LEDs) emitting at
520–525 nm were grown by metal-organic chemical vapor deposition by employing graded …
