Abstract

The rapid growth of triglycine sulfate (TGS) single crystals in the ferroelectric phase has been studied. The change in the structural imperfection and crystal habit as a function of supersaturation is demonstrated. The kinetic features of the polar face {010} growth are investigated. It is found that the kinetic curves depend on the effective supersaturation, which leads to nonzero crystal growth rates at zero supersaturation. It is also shown that, at a supersaturation σ < 7%, there is an anisotropy of the growth rates of the (010) and (0 \(\bar {1}\) 0) faces, which disappears at large supersaturations. The reasons for this behavior of the polar facet growth kinetics are discussed.
