← ScienceWhich outcome results when applying intense pressure to silicon?
A)Band gap energy decreases substantially✓
B)Reduced electron-phonon scattering occurs
C)Increased thermal conductivity is observed
D)Higher intrinsic carrier concentration develops
💡 Explanation
Applying intense pressure reduces interatomic spacing, thereby affecting the electronic band structure; the magnitude of the band gap decreases due to increased orbital overlap. Therefore, the band gap diminishes, rather than increased conductivity, because the pressure mainly impacts electronic energy levels.
