← ScienceWhich consequence results when wave functions overlap significantly in semiconducting nanocrystals?
A)Formation of minibands allowing conductivity✓
B)Increased optical energy gap size
C)Enhanced electron-phonon scattering rate
D)Suppressed quantum tunneling probability
💡 Explanation
The formation of minibands allowing conductivity results from overlapping wave functions because the increased spatial extent enhances electronic communication via quantum superposition (Bloch's theorem); therefore, conductivity increases, rather than other parameters changing.
