Ordered nanowire array blue/near-UV light emitting diodes.
ZnO-based light emitting diodes (LEDs) have been considered as a potential candidate for the next generation of blue/ near-UV light sources, [ 1 ] due to a direct wide bandgap energy of 3.37 eV, a large exciton binding energy of 60 meV at room temperature, and several other manufacturing advantages of ZnO. [ 2 ] While the pursuit of stable and reproducible p-ZnO is still undergoing, [ 3,4 ] het...
متن کاملMeasuring the Output of UV Light Emitting Diodes (LEDs)
As UV lamp technology changes, so must the tools we use. The evolution of UV LEDs to cure inks, coatings and adhesives is having an effect on UV measurement equipment and technique. UV LEDs are narrow bandwidth sources with typical emission in the 365-405 nm region. Contrasted to medium pressure UV microwave and arc lamps, which emit across a broad spectrum, UV LEDs have high output in a very l...
متن کاملDevelopment and future of ultraviolet light-emitting diodes: UV-LED will replace the UV lamp
Ultraviolet light-emitting diodes (UV-LEDs) have started replacing UV lamps. The power per LED of high-power LED products has reached 12 W (14 A), which is 100 times the values observed ten years ago. In addition, the cost of these high-power LEDs has been decreasing. In this study, we attempt to understand the technologies and potential of UV-LEDs.
متن کاملA Tale Of Two Spicules: The Impact of Spicules on the Magnetic Chromosphere
We use high-resolution observations of the Sun in Ca II H (3968Å) from the Solar Optical Telescope on Hinode to show that there are at least two types of spicules that dominate the structure of the magnetic solar chromosphere. Both types are tied to the relentless magnetoconvective driving in the photosphere, but have very different dynamic properties. “Type-I” spicules are driven by shock wave...
متن کاملSpicules-based competitive neural network
We present a new model of unsupervised competitive neural network, based on spicules. This model is capable of detecting topological information of an input space, determining its orientation and, in most case, its skeleton.
