← TechnologyWhich electrical conduction outcome primarily occurs when the doping concentration greatly increases in a semiconductor?
A)Increased band overlap, metallic conduction✓
B)Reduced carrier mobility, increased resistance
C)Enhanced piezoelectric effect, polarization
D)Quantized Hall effect, edge states
💡 Explanation
Increased doping causes more dopant atoms, resulting in increased band overlap leading to metallic conduction, because the Fermi level moves into the conduction or valence band, therefore, behaving like a metal, rather than exhibiting semiconducting behavior.
