← ScienceWhich change in outcome results when nitrogen atoms are substituted into a silicon lattice?
A)Band gap energy level increases✓
B)Phonon scattering decreases sharply
C)Electron mobility remains unaffected
D)Dielectric breakdown strength declines
💡 Explanation
Nitrogen creates nitrogen-vacancy centers which act as quantum defects, doping narrows the band gap, because these defects introduce localized energy levels within the silicon’s band structure; therefore, additional energy is needed to move electrons, rather than phonon alteration, at nitrogen concentration levels present.
