Which effect on electron wave functions results when a semiconductor quantum dot's dimensions approach the exciton Bohr radius?

💡 Explanation

When a quantum dot's size approaches the exciton Bohr radius, quantum confinement drastically increases because the electron and hole wave functions are compressed into a smaller volume, increasing their kinetic energy. Therefore increased quantum confinement energy results, rather than decreased recombination or modified dephasing, which depend on interface properties or phonon interactions.
