چکیده
InP-based 1 .6 tm microcavity light emitting diodes (MCLEDs) have been designed, fabricated and characterized. Oxideconfined MCLEDs with lateral aperture size down to 1 jtm have been realized with enhanced output slope efficiency and excellent spectral and spatial properties. Both mirror-free cylindrical MCLEDs with oxide-aperture and 3D MCLEDs have been fabricated and a maximum output power of 0.03 mW at 3OmA for a 30 im device has been realized. The effect of the aperture size on the slope efficiency and spatial properties have been systematically investigated, which shows an enhanced slope efficiency and narrower emission angle for small aperture size devices. The temperature dependent cavity properties have also been carefully examined for both the active region emission peak and cavity resonance peak.

InP-Based Cylindrical Microcavity Light-Emitting Diodes
We have investigated the properties of InP-based microcavity light-emitting diodes ( = 1 6 m). Our objective was mainly to study the effects of lateral confinement of optical modes, which was achieved by the wet oxidation of double In0 52Al0 48As layers. The smallest devices had a cavity radius of 0.5 m, which becomes comparable to where is the effective refractive index of the photon emitting ...

We propose and demonstrate weak-microcavity organic light-emitting diode (OLED) displays with improved light-extraction and viewing-angle characteristics. A single pair of low- and high-index layers is inserted between indium tin oxide (ITO) and a glass substrate. The electroluminescent (EL) efficiencies of discrete red, green, and blue weak-microcavity OLEDs are enhanced by 56%, 107%, and 26%,...

We have significantly improved the emission efficiency in an organic light emitting diode (OLEDs) based on tris(phenyl pyridine)iridium [Ir(ppy)3]. Using a semitransparent Ag with surface modification as anode to replace conventional ITO, excellent light outcoupling and hole injection properties have been realized. The Ag based OLED exhibits a maximum current efficiency of 81 cd/A and power eff...
