The distinct electrical properties and structural characteristics of nanoscale materials have attracted significant scientific interest. As material size is reduced to the nanoscale, its physical, chemical, optical, and electronic properties change drastically compared with its bulk form. Moreover, the incorporation of nanoparticles into electronic materials provides numerous advantages and helps in improving the performance of electronic devices by enhancing charge transport, increasing sensitivity, and reducing power consumption. At the nanoscale, quantum mechanical effects significantly influence the movement of charge carriers like electrons and holes, which leads to significant changes in electrical conductivity, carrier mobility, and the energy band structure of the material. In modern Electrical and Electronics Engineering, nanomaterials have been used increasingly to overcome the limitations of traditional conductive materials. The exceptional electrical conductivity of Carbon-based nanoparticles, including Graphene nanoparticles and Carbon Nanotubes, has been covered in this paper. Carbon-based nanomaterials like Graphene and Carbon nanotubes (CNTs) possess remarkably high electrical conductivity due to their interconnected carbon network and effective charge transfer mechanisms, and they also show exceptionally high electrical conductivity in comparison to metal oxide nanoparticles. Carbon Nanotubes and graphene show low electrical resistivity, high electron mobility, and good mechanical strength, making them highly ideal for applications in flexible electronics and nanoscale circuits, and they will play an important role in improving the efficiency, miniaturisation, and functionality of next-generation electronic devices.

Keywords:  Nanoparticles, electrical properties, electron mobility, flexible electronics, nanoscale circuits, low electrical resistivity, high electron mobility, good mechanical strength.
