New Silicon Study Findings Have Been Reported by Investigators at University of Technology

June 27, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Silicon. According to news reporting out of Chemnitz, Germany, by NewsRx editors, research stated, "Nanolithography by local oxidation of dodecyl-terminated silicon using a scanning probe microscope is a practical method for the generation of silicon oxide nanostructures on a well-defined substrate. We report on the functionalization of such structures by the selective binding of the cationic dye cresyl violet by electrostatic interactions."

Our news journalists obtained a quote from the research from the University of Technology, "The bound dye molecules could be optically excited and showed a clear luminescence emission. Additionally to the fluorescence light from monomers, an additional blue-shifted emission was found. This emission is an indication of the formation of charge-transfer complexes between the cationic dye molecules and anions in the oxide nanostructures."

According to the news editors, the research concluded: "AFM topography and fluorescence image of selectively cresyl violet modified silicon oxide nanostructures on alkyl-terminated silicon surfaces."
