Which outcome occurs when a semiconductor quantum dot is reduced in size, confining an electron's orbital?

💡 Explanation

When a quantum dot's size decreases, quantum confinement increases because the electron’s de Broglie wavelength becomes comparable to the dot size, raising the energy levels and thus increasing the band gap. Therefore, a larger band gap results, rather than decreased mobility, enhanced conduction, or reduced entanglement, which depend on different quantum mechanical and material properties.
