Which limitation appears when quantum dots are densely packed?

💡 Explanation

Electron tunneling widens the emission spectrum, because the reduced inter-dot spacing means the wave function of the quantum-dot electron orbitals overlap creating delocalization; therefore, electrons flow between dots causing energy variation rather than staying confined within a single dot.
