SUMMARY
Doped semiconductors exhibit a decreased band gap compared to pure semiconductors due to high doping levels. When impurity atoms are closely packed, they interact, causing the doping energy levels to split and form a doping band. This doping band can merge with the valence or conduction band, resulting in a narrower band gap. For further details, refer to the resource provided in the discussion.
