Keywords:
Carbon nanostructures, graphene, carbon nanotubes, graphene quantum dots, low-dimensional materials, nanotechnologyAbstract
Low-dimensional carbon-based nanostructures have attracted significant attention in recent years due to their exceptional structural, electrical, and optical properties. This study focuses on the development and characterisation of carbon nanostructures such as graphene, carbon nanotubes, graphene quantum dots, and carbon nanofibres through the analysis of previously reported experimental research. The investigation examines how synthesis techniques and structural parameters influence the morphology, crystallinity, and functional behaviour of these nanomaterials. The analysed findings indicate that reduced dimensionality plays a critical role in determining the electrical conductivity, electron mobility, and optical responses of carbon-based nanostructures. Two-dimensional graphene exhibits extremely high electrical conductivity, while one-dimensional carbon nanotubes demonstrate efficient charge transport along their cylindrical structures. Graphene quantum dots show strong photoluminescence behaviour due to quantum confinement effects. The study highlights that advanced characterisation techniques such as electron microscopy and Raman spectroscopy are essential for understanding the structural and functional properties of these materials. The findings demonstrate that low-dimensional carbon nanostructures possess significant potential for applications in nanoelectronics, sensing technologies, energy storage systems, and optoelectronic devices.
