2016-05-12 Tech breakthrough boosts 2D semiconductor photoluminescence by 20,000-fold
National University of Singapore researchers said the discovery could pave the way for the application of 2D semiconductors such as tungsten diselenide in advanced optoelectronic and photonic devices.
2012-11-05 Solar cells checked by high power diode laser line generator
This technology is designed to add to the changing energy policy: a line laser is able to scrutinise solar cells using the so-called photoluminescence spectroscopy.
2016-03-31 Investigating the impact of etching time on 4H-SiC defects
In this article, we looked into the relationship between the pre-growth hydrogen etching time and defects density on 4H-SiC substrate surfaces.
2015-10-29 Sub-nm perovskite nanocrystals to yield energy-efficient LEDs
LMU researchers synthesised perovskite nanocrystals in the form of ultrathin nanoplatelets that feature emission characteristics that are tunable by altering their thickness.
2008-08-27 IBM demos electric control of light-emitting nanotubes
Electric control of the spectrum, direction and efficiency of light-emitting nanotubes (LENs) has been demonstrated by researchers at IBM Corp.'s Thomas J. Watson Research Center, bringing silicon photonics one step closer to reality.
2005-11-21 IBM claims better LED
IBM Corp. unveiled Thursday (Nov. 17) what is said is the world's first electroluminescent nanotube transistor and claimed it glows 1000 times brighter than a light-emitting diode.
2015-12-02 Carbon-reducing technologies target climate change
There is little doubt that the climate is heating up and that it is due to the production of greens-house gases, which have been steadily increasing since the maturation of the industrial revolution.
