OLEDs have been researched for application in display devices due to their considerable advantages. In order to further improve and optimize devices for practical applications, the electrical and optical parts

Since lighting is estimated to account for 20% of the world’s electricity consumption, the search for reliable and efficient lighting technologies to replace incandescent and fluorescent modules is intense.

The light source on short wavelenghts has been researched in GaN-based lser diodes (LDs). For high efficiency emitting devices, the wave-guide layer has been investigated to obtain more stable far

The addition of a chlorine species during thermal oxidation of silicon results in improved threshold stability, higher and more uniform oxide dielectric strength and improved junction properties due to lower
