← ScienceWhich outcome results when specific frequencies irradiate crystal lattice defects?
A)Phonon scattering impeding thermal conductivity✓
B)Increased electron-hole pair recombination rate
C)Plasmon generation enables surface reactions
D)Enhanced exciton binding energy stabilization
💡 Explanation
Phonon scattering leads to inefficient heat transfer arising when irradiation imparts energy in certain crystal defects. This triggers phonon scattering, because the defect absorbs incident photons, therefore reducing thermal conductivity, rather than enhancing electron transitions which would serve other purposes.
