G. Arunmozhi et al., GROWTH AND SURFACE STUDIES ON TRIGLYCINE SULFO-PHOSPHATE (TGSP) SINGLE-CRYSTALS, Materials science & engineering. B, Solid-state materials for advanced technology, 49(3), 1997, pp. 216-220
Growth of triglycine sulpho-phosphate (TGSP) crystals using fabricated
and as grown seeds and at three different pH values is reported. Larg
e size crystals with wide plane perpendicular to the ferroelectric axi
s have been grown by adjusting the pH of the solution and by choosing
c-cut seeds. Morphological changes due to pH variations have been iden
tified. Optical microscopic examination of the freshly harvested cryst
al surface reveals etch pits, spirals and flat topped hillocks. A scan
ning electron microscope, in the secondary electron emission mode has
been employed to observe the cleavage surface and domain structure on
TGSP crystal without metallization of the surface. Low accelerating vo
ltage and low probe current have been used to probe the surface to avo
id the charging effect. In the absence of charging effect the domains
observed are found to be static. There is no change in the domain stru
cture due to phosphate addition. (C) 1997 Elsevier Science S.A.
