← ScienceWhich consequence results when doping alters silicon's crystal lattice?
A)Fermi level shifts position✓
B)Debye length increases linearly
C)Critical temperature decreases sharply
D)Dielectric constant remains constant
💡 Explanation
Dopants introduce energy states, altering the electron-hole balance and shifting the Fermi level via band bending because the additional carriers shift the equilibrium. Therefore, the Fermi level changes rather than the Debye length, critical temperature, or dielectric constant because those depend more directly on interatomic spacing and polarization.
