| Popis: | The effect of synthesis conditions and incorporation of heteroatoms on the structure and morphology of few-layer graphene nanoflakes is investigated using Raman spectroscopy, X-ray photoelectron spectroscopy, and electron microscopy. It is found that doping with nitrogen forms defects inside graphene layers, while incorporation of silicon in contrast results in their bending and the formation of interlayer defects. Increasing the synthesis temperature reduces the number of defects in the material via graphitization and increase in the number of layers. |
