ScholarBank@NUS Repository. https://doi.org/10.1088/1742-6596/28/1/022 | Abstract: | Detailed polarized Raman study was performed on KIO3 single crystals over 78.5-553K, which show a strong central component in the high temperature phase I and two soft modes S1 and S2 related to the phase transitions I-II and II-III respectively. The phonon dispersion of KIO3 in phase I was calculated, utilizing density functional perturbation theory (DFPT) and local density approximation (LDA). The KIO 3 single crystals were ascribed to improper ferroelectrics with the phase transition series from rhombohedral phase I, to monoclinic phase II, to triclinic phase III, and phase IV. © 2006 IOP Publishing Ltd. | Source Title: | Journal of Physics: Conference Series | URI: | http://scholarbank.nus.edu.sg/handle/10635/97520 | ISSN: | 17426588 | DOI: | 10.1088/1742-6596/28/1/022 |
