How Does the Photoelectric Effect Work at the Nanoscale?
At the nanoscale, the quantum confinement effect becomes prominent. When the size of the material is reduced to the nanometer scale, the energy levels become discrete, which can increase the efficiency of the photoelectric effect. Nanostructures such as quantum dots, nanowires, and nanoparticles can be engineered to optimize the absorption of light and the emission of electrons.
