    • Raman spectra with the 442 nm excitation (below the ZnO band gap) are dominated by the E2 high phonon mode (a nonpolar mode), whereas the LO phonon modes (polar modes) become stronger with the 325 nm excitation (resonant with the ZnO band gaenergy) due to the strong interaction between the electric dipoles associated with these phonon modes and photogenerated electron-hole pairs.
