Which consequence results when the crystal lattice of a silicon-germanium alloy in a thermoelectric generator absorbs excessive neutron radiation?

💡 Explanation

Excessive neutron radiation causes lattice defects, introducing scattering centers; point defects increase. This reduces long-range order, decreasing the mean free path for electrons and phonons, diminishing the Seebeck coefficient, therefore weakening therm electric generation rather than increasing conductivity or enhancing other carrier activity, because high lattice order is needed.
