Studies on Resonant Interference in Frerroelectric Barium Titanate |

Abstract: | Abstract Raman spectrta of barium titanate are examined.A_1(LO)modes at 196 and 474 cm~(_1) are recoded with asymenetric cut-off on low-energy sides,manifesting a resonant inteference with a positive Fana conpling coefficient.Green’s function method is used to investigate the hybridization of the reso-nances with single optical phonon state. |
