Which outcome occurs when two quantum dots are placed in close proximity?

A)Charge transfer increases between dots
B)Exciton decay accelerates dramatically
C)Dots' energy levels become degenerate
D)Phonon scattering rate gets suppressed

💡 Explanation

When quantum dots are very close, the quantum tunneling mechanism allows electron wavefunctions to overlap, and thus allows more charge to flow; because the electrons transfer effectively, it increases charge transfer rather than any other effect.
