Within semiconductor nanocrystals, which effect limits electron-hole recombination efficiency?

A)Surface trap state concentration
B)Phonon energy quantization
C)Quantum dot size uniformity
D)Exciton diffusion coefficient

💡 Explanation

Recombination efficiency is reduced because dangling bonds create surface trap states that capture carriers via the process of surface passivation; therefore, surface trap state concentration limits electron-hole recombination, rather than phonon modes or diffusion because the unpassivated nanocrystal surface dominates behavior.
