A study is made of the effect of temperature and hydrostatic pressure on the permittivity, forbidden-band width, electrical conductivity, and photoconductivity of crystals of Sn2P2S6. The empirical results obtained indicate that a new phase-transformation line exists on the p-T diagram of Sn2P2S6 p > 0.17 GPa. This phase transformation is evidently a second-order transition, separating a paraelectric, proportionate phase from an intermediate, possibly nonproportionate phase. The results also indicate similarity of the p-T diagram of Sn2P2S6 to the x-T diagrams of ferroelectric solid solutions of Sn2P2(SexS1-x)6. |
