Abstract:Nanostructured graphite and few-layer graphene (FLG) have been grown on copper and silicon substrates via pulsed laser deposition (PLD). Our PLD setup utilizes a high power Nd:YAG laser (266 and 532 nm) to ablate a solid target in high vacuum (10-6 torr), depositing the material as a thin film onto a substrate. The growth mechanism is highly dependent on several experimental parameters. How these parameters affect the resulting film is examined in detail in an effort to develop a better understanding of the underlying growth mechanisms of carbon nanostructures. Parameters such as substrate temperature, target and substrate morphology, laser wavelength, and laser flux are all examined in detail, and results are given based on how these experimental factors affect the growth mechanism of the thin films. Raman spectroscopy and SEM are used to analyze the samples.
