| Abstract: | Size effect on the fundamental properties of Sn2P2S6 ferroelectric is studied. The decrease of Raman peak frequency, accompanied by the band broadening and asymmetry, is observed in the spectra of microcrystalline Sn2P2S6 powder. Theoretical calculations, performed in the ANNNI model for Sn2P2S6 microcrystals of different size, predict the decrease of the ferroelectric phase transition temperature with the decrease of the microcrystal size parameter. |
