Nanostructures

Nanostructures are materials or systems with at least one dimension in the nanometer scale, typically between 1 and 100 nanometers. At this scale, physical properties differ significantly from bulk materials due to quantum confinement, surface effects, and reduced dimensionality. Nanostructures include nanoparticles, nanowires, nanotubes, and thin films. Their electronic, optical, mechanical, and thermal properties can be engineered by controlling size, shape, and composition. Nanostructures are central to nanotechnology and modern materials science. They enable applications in electronics, photonics, medicine, and energy conversion. In physics, nanostructures provide platforms to study quantum effects in confined systems. Their high surface-to-volume ratio enhances chemical reactivity and sensing capabilities. Understanding nanostructures is essential for designing next-generation devices with improved performance and novel functionalities.
