It was about 125 years ago that the light bulb was commercialized by Thomas Edison. No doubt a brilliant invention at the time, today its low power conversion efficiency is one of the reasons why lighting in the western world has such high energy consumpti ...
We present a study on the improvement of the external Quantum Efficiency (QE) of Gallium-Nitride-based Light Emitting Diodes (LEDs) by the use of the Single Mirror (SMLED) design [N.E.J. Hunt et al., Electron. Lett. 28, 2169 (1992)]. Three different substr ...
This paper describes a method for modeling the natural peeling phenomenon over any 3D surface. Using crack input data—precomputed with a semi-physical solution—this method allows simulating peeling on any type of triangulated 3D object. Our model’s main ad ...
This article describes a method for modeling the propagation of cracks on any 3D surface. Taking a previous cellular automata model as basis, this method allows any type of cracks on any type of triangulated 3D object. Our model's main advantage is that it ...
We are progressively approaching the physical limits of microcavity LEDs (MC-LEDs) for high brightness, high efficiency LEDs. They are promising high efficiency devices and they offer the very attractive prospect of full planar fabrication process. However ...
We present a study on the dependence of the external Quantum Efficiency (QE) of Light Emitting Diodes (LEDs) on the device properties and p-contact metallisation. The external QE could be doubled by changing the p-type contact from oxidised Ni/Au to non-an ...
