Effect of carbon ion-beam irradiation on graphene oxide film

Tunable Wettability and Conductivity of the Graphene Oxide Surface with Insights from Density Functional Theory and Molecular Dynamics Investigations

“…For instance, the irradiation peak positions shifted to 11.02 and 11.27° corresponding to d spacings of 4.029 and 3.941 Å at ion fluences of 8 × 10 15 and 3 × 10 16 ions·cm –2 , respectively. This indicates a decrease in interplanar spacing with ion fluence . This may be because of the ion-induced removal of a functional group from the basal plane and in between the layers.…”

“…18 The disorder parameter represents the disorder in materials. 18 After the baseline corrections, the disorder parameters of all samples have been calculated using the ratio of peak height. For the nonirradiated sample, the value of the disorder parameter is 0.98, which decreases with increasing ion fluence and becomes 0.79 and 0.72 at fluences of 8 × 10 15 and 3 × 10 16 ions•cm −2 , respectively.…”

“…In carbon-based materials, the disorder in the lattice parameter is measured by the ratio of the intensity of the D peak and the G peak (I D /I G ), which is known as the disorder parameter. 18 The disorder parameter represents the disorder in materials. 18 After the baseline corrections, the disorder parameters of all samples have been calculated using the ratio of peak height.…”

“…The D peak arises due to disorder in the graphene structure. In carbon-based materials, the disorder in the lattice parameter is measured by the ratio of the intensity of the D peak and the G peak ( I D / I G ), which is known as the disorder parameter . The disorder parameter represents the disorder in materials .…”
