Quantum Mechanics for NanoScience - A Comprehensive Review

Nanoscience and nanotechnology focus on the study and application of materials whose Nanoscience and nanotechnology deal with the study of materials and devices at nanometer dimensions where unique physical and quantum properties are observed. Miniaturization of systems improves mechanical response, thermal behavior, and electronic performance. This work discusses important nanoscale phenomena such as size effects, frictionless molecular motion, Bohr’s atomic model, excitons, carbon nanotubes, and quantum dots. The study also explains how quantum confinement changes the optical properties of nanomaterials and enables advanced technological applications in electronics, sensors, and photonic devices.
