← ScienceWhich 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.
