← ScienceWhich outcome occurs when excessive doping occurs in germanium crystal?
A)Conductivity approaches metallic levels✓
B)Band gap increases significantly
C)Intrinsic carrier concentration lowers
D)Debye screening length increases
💡 Explanation
Conductivity increases sharply because donor/acceptor concentration surpasses intrinsic carriers, causing degenerate semiconductor behaviour. Therefore it turns into a poor metallic conductor rather than becoming insulating, where the band gap would matter.
