Which phenomenon primarily limits miniaturization density dependent on electron wave functions within semiconductor quantum dots?

💡 Explanation

When quantum dots are closely packed, significant wavefunction overlap occurs between dots because of quantum tunneling, leading to electrons escaping their intended locations, reducing confinement. Therefore tunneling limits miniaturization, rather than phonon scattering, coulomb repulsion, or surface recombination which do not impact electron localization in nearby, functional quantum dots.
