Gram-scale quantities of graphene sheets can be synthesized in a bottom-up chemical approach and we have sought to address the extent of the defect density using various characterization techniques which include X-ray diffraction, high resolution transmission electron microscopy, single area electron diffraction, Raman spectroscopy, atomic force microscopy and X-ray photoelectron spectroscopy. It...
Excimer Pulse laser Deposition (PLD) is used to grow thin carbon films where C60 precursor is used as target. The effect of nitrogen (N2) incorporation is observed by varying the N2 partial pressure. When the film is deposited in N2 free environment it is damaged by high energetic laser beam irradiation and it becomes amorphous. With the increase of N2 partial pressure the film becomes more polymerized...
