Synthesis, properties, and structure of potassium titanyl phosphate single crystals doped with chromium

摘要

Chromium-doped potassium titanyl phosphate single crystals have been synthesized and their physical properties have been studied. Doping with chromium barely affects the temperature of the ferroelectric phase transition but significantly reduces conductivity (by almost two orders of magnitude). A precise Xray diffraction study of K1.00Cr0.02Ti0.98OPO4 and K0.996Cr0.005Ti0.995OPO4 crystals has shown that chromium atoms are located near sites of titanium atoms.
