Lattice dynamics and phase transitions in KNbO3 and K0.5Na0.5NbO3 ceramics
Phonons in both ceramic samples KNbO(3) (KN) and K(0.5)Na(0.5)NbO(3) (KNN-50) were investigated from 10 to 900 K by means of Raman, infrared, and THz spectroscopy. First-order transitions from cubic to tetragonal phases were detected at about 755 K (in KN) and 710 K (in KNN-50), where the first comp...
