Which doping outcome occurs when excessive annealing affects semiconductors?

💡 Explanation

Annealing can redistribute dopants, causing band modifications because dopant diffusion into grain boundaries result in increased band tailing. Therefore, reduced carrier mobility is observed, rather than carrier freeze-out confined grain depletion regions.
