Which consequence results when a crystal lattice contains doping atoms?

A)Localized states enter the bandgap
B)Increased phonon-mediated thermal conductivity
C)Wider range of transparent wavelengths
D)Reduced Debye temperature amplitude limit

💡 Explanation

Doping atoms alter the periodic potential; therefore intrinsic energy levels occur within the forbidden gap because the translational symmetry is disrupted by the introduction of impurities, rather than different thermal or phonon properties.
