Abstract

We have employed Raman spectroscopy in order to study the mechanism of the significantly increased ferroelectric phase transition temperatures in proton-irradiated K(H_1−x D_x)₂PO₄ crystals. Prominent changes occurred in the asymmetric stretching vibration mode frequency of D₂PO₄ molecules in the proton-irradiated crystals, thus stating the role of the lattice coupled to H/D.
