← ScienceWhich transport mechanism increases when quantum dots are closely packed?
A)Resonant energy transfer (FRET)✓
B)Ohmic contact resistance increase
C)Dielectric breakdown susceptibility
D)Electromagnetic interference shielding increases
💡 Explanation
Closely spaced quantum dots enhance dipole-dipole interactions, increasing Förster resonance energy transfer (FRET) because the rate’s inverse sixth-power dependence on distance favors higher transfer rates; therefore, FRET increases rapidly with proximity, rather than other scattering effects.
