Which property change of a semiconductor occurs when dopant atoms introduce energy levels within the band gap?

💡 Explanation

When dopant atoms are introduced, they create new energy levels (orbitals) within the band gap of the semiconductor because the dopant's electronic structure influences the semiconductor's overall orbital configuration, allowing electrons to jump across the gap. Therefore, conductivity increases due to the available charge carriers, rather than structural stability or radiation resistance which involve different mechanisms.
