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.

Dopant control over the crystal morphology of ceramic materials

“…The presence of the dopants can also modify the relative energy of the different crystal faces, thus yielding a way to control the crystal morphology, and ultimately the type and number of surface sites exposed. Experimentally it is well established that different dopants can alter both crystal shape and size, but little is known about the atomistic details of this effect [4][5][6]. Computer modeling is an obvious candidate to fill this gap, and being able to predict the stable morphology of crystals modified by different types and quantities of dopant ions would open up a new field of research in computational materials science, in which the crystal properties can be designed simultaneously at the atomic (surface structure and composition) and mesoscopic (morphology, i.e.…”

Growth of Triglycine Sulfate Single Crystals Doped with Pt(IV) and l-Alanin

“…6 The growth process was performed in the range of 45-30°C; the temperature was controlled by an automatic program with a cooling rate of 0.02°C/h. A survey of selected doped LATGS/ Pt(IV) grown crystals is in Table 1.…”

Crystal growth, structural perfection, phase transition, optical, and etching studies of doped glycine phosphite ferroelectric single crystals

“…The Doping of cobalt (II) phosphate in TGSP crystal resulted in good quality crystals with a stable domain structure [8]. Doped TGSP crystals with amino acids such as L-alanine (L-ATGSP) and L-asparagine (ASP-TGSP), were investigated for further improvement in their pyroelectric property [9].…”
