Investigation of the Electrical and Optical Properties of Nanomaterials
Main Article Content
Abstract
Nanomaterials have attracted considerable attention in recent years due to their unique electrical and optical properties that emerge at the nanoscale. This study investigates the electrical conductivity, charge transport behaviour, optical absorption, and photoluminescence characteristics of nanomaterials through a comprehensive secondary analysis of existing scientific literature. The research examines how nanoscale structural parameters such as particle size, morphology, crystal structure, and surface modification influence the functional performance of various nanomaterials, including semiconductor nanoparticles, metal oxide nanostructures, and carbon-based nanomaterials. The findings indicate that quantum confinement, surface plasmon resonance, and enhanced surface-to-volume ratios significantly affect the electronic and optical behaviour of these materials. Carbon-based nanomaterials such as graphene and carbon nanotubes exhibit superior electrical conductivity, while semiconductor quantum dots and metal nanoparticles demonstrate tunable optical responses. The study highlights the importance of nanoscale engineering in tailoring the electrical and optical properties of nanomaterials for advanced applications in electronics, optoelectronics, sensing technologies, and renewable energy systems.
