Which outcome occurs when dopants alter silicon band structure?

A)Increased conductivity at specific wavelengths
B)Lower critical temperature for superconductivity
C)Significant Hall voltage diminishes sharply
D)Lattice dislocations spontaneously self-correct themselves

💡 Explanation

The electrical property change arises from Fermi level adjustment after doping. Because the band gap dictates conductivity, injected carriers reduce resistance, thereby increasing conductance rather than superconductivity, and lattice restructuring; other phenomena do not occur spontaneously, rather than due to doping.
