UNLABELLED The green polymer light emitting diodes (PLEDs) were fabricated using the solution precursor synthesis method. To improve the device's electrical. and optical properties, gold (Au) nanoparticles (NPs) were added to the hole injection layer (HIL) with poly(3,4-ethylene- dioxythiophene):poly(styrenesulfolnate) ( PEDOT PSS) organic material. The(More)
The Korea Superconducting Tokamak Advanced Research (KSTAR) device site assembly was completed by May 2007. During the assembly period, several key technologies were developed to assemble the superconducting tokamak and its ancillary systems. As will be described in this paper, we encountered several problems and difficulties that mainly stemmed from the(More)
