Graphene patterning by nanosecond laser ablation: the effect of the substrate interaction with graphene
This paper focuses on the development of patterned graphene/substrate by means of green nanosecond pulse laser irradiation. Monolayer graphene samples supported on a Si/SiO2 substrate were patterned using 532 nm laser irradiation under fluence conditions ranging from 31 mJ/cm2 and to 4240 mJ/cm2. Raman spectroscopy was used to investigate the effect of laser irradiation on the graphene. It was found that at 356 mJ/cm2 selective ablation of the graphene occurs. However, at fluence values above 1030 mJ/cm2 (when damage to the substrate is observed) no ablation of the graphene takes place. In contrast, its graphenic structure was found to have been modified. Only at fluence values where the ablation of the substrate occurs, is graphene eliminated in an area almost equivalent to that of the ablated substrate. In this case, additional damage to the graphene sheet edges is produced. The increment in the number of oxygenated functional groups in these regions, as measured by XPS spectroscopy, suggests that this damage is probably caused by thermal phenomena during the ablation of the substrate.

description |
This paper focuses on the development of patterned graphene/substrate by
means of green nanosecond pulse laser irradiation. Monolayer graphene samples
supported on a Si/SiO2 substrate were patterned using 532 nm laser irradiation under
fluence conditions ranging from 31 mJ/cm2 and to 4240 mJ/cm2. Raman spectroscopy
was used to investigate the effect of laser irradiation on the graphene. It was found that
at 356 mJ/cm2 selective ablation of the graphene occurs. However, at fluence values
above 1030 mJ/cm2 (when damage to the substrate is observed) no ablation of the
graphene takes place. In contrast, its graphenic structure was found to have been
modified. Only at fluence values where the ablation of the substrate occurs, is graphene
eliminated in an area almost equivalent to that of the ablated substrate. In this case,
additional damage to the graphene sheet edges is produced. The increment in the
number of oxygenated functional groups in these regions, as measured by XPS
spectroscopy, suggests that this damage is probably caused by thermal phenomena
during the ablation of the substrate. |
