New Nanotubes Study Findings Reported from University of Munich (Antenna-Enhanced Optoelectronic Probing of Carbon Nanotubes)

August 20, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- New research on Nanotubes is the subject of a report. According to news reporting out of Munich, Germany, by VerticalNews editors, research stated, "We report on the first antenna-enhanced optoelectronic microscopy studies on nanoscale devices."

Our news journalists obtained a quote from the research from the University of Munich, "By coupling the emission and excitation to a scanning optical antenna, we are able to locally enhance the electroluminescence and photocurrent along a carbon nanotube device. We show that the emission source of the electroluminescence can be pointlike with a spatial extension below 20 nm."

According to the news editors, the research concluded: "Topographic and antenna-enhanced photocurrent measurements reveal that the emission takes place at the location of highest local electric field indicating that the mechanism behind the emission is the radiative decay of excitons created via impact excitation."
