← ScienceWhich risk increases when an electron's wavefunction overlaps a nonsymmetrical potential well?
A)Increased radiative emission linewidth
B)Decreased Auger recombination lifetime
C)Enhanced intervalley scattering rate✓
D)Elevated dielectric breakdown threshold
💡 Explanation
Enhanced intervalley scattering rate increases because asymmetrical potential wells cause electrons to have momentum mixing between valleys, therefore changing selection rules; thus rather than other options like radiative emission, scattering probability is affected by symmetry.
