dc.description.abstractThe modification of single layer graphene due to intense, picoseconds near-infrared laser pulses is investigated. We monitor the stable changes introduced to graphene upon photoexcitation using Raman spectroscopy. We find that photoexcitation leads to both a local increase in hole doping and a reduction in compressive strain. Possible explanations for these effects, due to photo-induced oxygenation and photo-induced buckling of the graphene, are discussed.en_GB

dc.descriptionFile "01 flake before modification.jpg" is a microscope picture of a monolayer graphene flake before photomodification. Files "02 Raman map before modification 2D.txt" and "02 Raman map before modification G+D.txt" contain Raman data for the flake before modification. The columns in the files are [X coordinate; Y coordinate; Raman shift; intensity;]. The first file contains data for Raman shifts from 2470 to 2916 cm-1, the second file - data for shifts from 1306 to 1840 cm-1. File “03 PL image before modification.tif” is an Up-converted photoluminescence image of the flake before photomodification. File “04 PL image after modification.tif” is an Up-converted photoluminescence image of the flake after photomodification. File “05 flake after modification.jpg” is a microscope picture of a monolayer graphene flake after photomodification. Files “06 Raman map after modification 2D.txt” and “06 Raman map after modification G+D.txt” are Raman data for the flake after modification. File “07 AFM data.txt” is AFM data for a modified area of a monolayer graphene sample.en_GB
