← ScienceWhich outcome occurs when vibrational mode overlap increases substantially in coupled quantum-dot wave functions?
A)Resonant energy transfer accelerates✓
B)Quantum decoherence becomes instantaneous
C)Phonon scattering rate decreases
D)Exciton binding energy abruptly drops
💡 Explanation
Resonant energy transfer becomes more efficient because the increased vibrational mode overlap enhances the **Förster resonance energy transfer** (FRET) rate. Therefore, energy transitions proceed quickly, rather than slowly due to lattice impedance or thermal gradients.
