Which outcome occurs when a quantum dot's wave functions are highly compressed by design?

A)Increased electron-electron Coulomb repulsion
B)Decreased quantum tunneling probability
C)Reduced radiative recombination efficiency
D)Suppressed electron-phonon interactions

💡 Explanation

Increased spatial confinement causes a stronger electron-electron Coulomb repulsion rather than other effects, because wave functions overlap more. Therefore, electron interactions increase because the confinement energy dominates, rather than tunneling or electron-phonon energies given size.
