Which mechanism limits electron mobility near the band edges?

A)Anderson localization narrows available states
B)Bose-Einstein condensation becomes more probable
C)Fermi level approaches a singularity
D)Phonon scattering decreases energy dissipation

💡 Explanation

Anderson localization confines electron wavefunctions because disorder induces quantum interference effects near the band edges, impeding transport. Therefore, mobility decreases near these energy levels, rather than increasing from condensation or Fermi effects.
