Which consequence results when substitutional impurity doping modifies silicon crystal structure?

💡 Explanation

The introduction of substitutional impurities changes the unit cell leading to changes in the crystal lattice and lattice vibrations. Impurity scattering disrupts the periodic potential; altering the Phonon dispersion relation because translational symmetry is broken, therefore affecting thermal and electrical conductivity, rather than intrinsic frequency shifts or recombination suppression.
