Abstract
Two-dimensional materials have
attracted significant attention due to their outstanding electrical, optical,
and mechanical properties. Among them, graphene, a single layer of sp2-bonded
carbon atoms arranged in a hexagonal lattice, exhibits exceptionally high
carrier mobility and optical transparency, making it a promising material for
plasmonic and optoelectronic applications, where film uniformity and layer
control are of critical importance. In this study, single-wall graphene was
dispersed in N-methyl-2-pyrrolidone (NMP), and the suspension obtained after
ultrasonic treatment and centrifugation was deposited onto glass substrates by
the drop-coating method. Multilayer films consisting of 2, 4, 6, and 8 layers
were fabricated by applying 50 µL of solution per layer. After each deposition,
the samples were dried at 80 °C for 10 minutes, followed by annealing at 200 °C
for 1 hour. The structural and morphological properties of the graphene thin
films were characterized by X-ray diffraction (XRD) and scanning electron
microscopy (SEM), while their elemental composition was examined using energy
dispersive X-ray spectroscopy (EDS). The influence of the number of graphene
layers on film homogeneity, surface morphology, and structural arrangement was
comparatively investigated. The influence of the number of graphene layers on
film homogeneity, surface morphology, and structural arrangement was
comparatively investigated, and the 8-layer graphene film was found to exhibit
the most homogeneous and continuous surface morphology among all samples.
