Just have a look at light that is forbiddenA crystal with a ‘3D photonic band gap’ is a powerful tool to control light. New types of solar cells, sensors and miniature lasers can highly benefit from this. Inside a man-made crystal like this, a range of light wavelengths is forbidden. Until now, the characteristic wavelength region is determined by using theoretical models. These idealized models have clear shortcomings. Researchers of the University of Twente (MESA+) now developed a fully experimental method of determining the band gap, literally making visible the unseen. They present their results in Optics Express, by the Optical Society of America.Read more
Looking inside 3D nanostructures without leaving a traceDiscovering what is inside a three-dimensional (3D) nanostructure, is no longer a matter of cutting slices, thus breaking it up and destroying its functionality. Scientists from the University of Twente and the European Synchrotron Radiation Facilty (ESRF) discovered a new method to look deep inside a 3D nanostructure. This ‘traceless X-ray tomography’ (TXT) can be used for photonics, electron chips and memories, for example. The results are published in the ‘ACS Nano’ journal of the American Chemical Society.Read more
