Findings from International University Yields New Data on Nanodots (Engineering the strain in graphene layers with Au decoration)

July 2, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- New research on Nanodots is the subject of a report. According to news reporting originating in New Delhi, India, by VerticalNews journalists, research stated, "Graphene sheets decorated with Au nanodots are synthesized by deposition of Au of three different thicknesses and subsequent annealing at 400 degrees C. Different thicknesses of Au film for the formation of Au nanodots on graphene are measured using Rutherford backscattering spectrometry and morphology is studied using scanning electron microscopy. Raman spectroscopy indicates 3-6-fold increase in I-D/I-G ratio depending on the content of Au deposited on graphene."

The news reporters obtained a quote from the research from International University, "The increase in disorder in Au decorated graphene layers is explained on the basis of interaction of Au atoms with Pi bonds of graphene. The splitting and blueshift in G band signifies compressive strain in Au deposited graphene."

According to the news reporters, the research concluded: "X-ray diffraction studies using synchrotron radiation source confirm compressive strain in graphene, which increases with increase of Au film thickness."
