Journal ArticleDOI
III -nitride photonic-crystal light-emitting diodes with high extraction efficiency
TL;DR: In this article, a photonic-crystal structure for superior optical mode control was proposed for blue light-emitting diodes with a light extraction efficiency of 73% using InGaN-GaN devices.
Journal ArticleDOI
Experimental measurement of the photonic properties of icosahedral quasicrystals
TL;DR: Three-dimensional icosahedral quasicrystals exhibit sizeable stop gaps and, despite their quasiperiodicity, yield uncomplicated spectra that allow us to experimentally determine the faces of their effective Brillouin zones, confirming that they are excellent candidates for photonic bandgap materials.
Journal ArticleDOI
Creating Periodic Three-Dimensional Structures by Multibeam Interference of Visible Laser
TL;DR: In this article, face-centered cubic-like lattices with periods of 0.9 μm were created by interference of multiple visible laser beams on photosensitive epoxy, and defect-free porous structures were obtained in an area covered by the laser beams.
Journal ArticleDOI
Magnetic biochips: a new option for sensitive diagnostics
TL;DR: In this article, the authors present an overview of miniaturized biosensor devices based on the sensitive detection of magnetic nanoparticles using the giant magneto-resistance effect, which has advantages over established methods, and the sensitivity is promising.
