Which effect happens when applying extreme pressure on silicon, decreasing interatomic distance?

💡 Explanation

Applying pressure forces atoms closer causing orbital overlap. Band gap decreases because of increased electron delocalization (band broadening), leading to metallization; therefore, the material conducts rather than remaining a semiconductor like normal silicon.
