Domain configurations in domain engineered 0.955Pb(Zn(sub 1/3)Nb(sub 2/3))O3-0.045PbTiO3 single crystals

An optical microscopy study on the domain structures of 0.955Pb(Zn(sub 1/3)Nb(sub 2/3))O3-0.045PbTiO3 rhombohedral phase single crystals poled along [001] of the cubic coordinates is reported. The study showed that the domain patterns in the domain engineered PZN-4.5%PT single crystals are predominantly twins containing only two of the four possible domains after being poled in [001].
