Fabrication of two-dimensional InGaN-based micro-LED arrays

We have successfully fabricated two-dimensional InGaN-based 12 × 12 micro-light emitting diode (LED) arrays with individually addressable emitters having diameters of 8 and 12 m. A new planarisation scheme including gap-filling with plasma enhanced chemical vapour deposition (PECVD) SiO2 and a chemical-mechanical polishing process was successfully developed for the electrical isolation of individual diodes. The uniformity of elements within an array was demonstrated through their electroluminescence and I-V characteristics

Traceable dynamic measurement of mechanical quantities: objectives and first results of this european project

Nine european national metrology institutes (NMIs) are collaborating in a new project funded by the european metrology research programme (EMRP) to establish traceable dynamic measurement of the mechanical quantities force, pressure, and torque. The aim of this joint research project (JRP) is to develop appropriate calibration methods, mathematical models, and uncertainty evaluation. The duration of the project is 3 years for a global amount of €3.6 million. It began in September 2011

(AlGaIn)N ultraviolet LED chips and their use in tri-phosphor luminescence conversion white LEDs

We report on the development of (AlGaIn)N quantum well LEDs covering the 380 to 430 nm wavelength range, which serve as the primary light source for tri-phosphor luminescence conversion white LEDs. Epitaxial layer growth was performed by low-pressure metal-organic chemical vapor deposition on sapphire substrates. Mesa LEDs were fabricated and either mounted in standard epoxy-based 5 mm radial LED packages or flip-chip bonded on ceramic submounts. Then, LED-chips with peak wavelengths matching the absorption spectrum of an appropriately chosen inorganic tri-phosphor blend, were used for the fabrication of single-chip tri-color luminescence conversion white LEDs. These devices allowed us to demonstrate the feasibility of the above concept for improved color rendering and tunability
