Growth of Triglycine Sulphate Single Crystals Doped by Cobalt (II) Phosphate

Abstract

Modified TGS single crystals have been grown by doping with Cobalt (II) Phosphate in ferroelectric phase. The effects of different amounts of doping entities on the growth habit and P-E hysteresis loop have been investigated. The experimental results show that while the spontaneous polarization Ps measured on variously doped crystals remains virtually unchanged, the coercive field values differ in dependence on the growth conditions and grown pyramidal features. The highest values of the coercive field Ec have been found to fall in the interval 800-900 V/cm.
