← ScienceWhich electrical characteristic results when dopants modify band gaps?
A)Increased semiconductor conductivity✓
B)Enhanced electron tunneling
C)Reduced breakdown voltage
D)Greater dielectric strength
💡 Explanation
Increased semiconductor conductivity occurs because doping introduces charge carriers within the band gap, altering the Fermi level and increasing carrier concentration in the conduction or valence bands; therefore doping increases conductivity, rather than reducing breakdown or enhancing tunneling, because doping changes bulk properties not potential barrier widths.
