P. Urenski et G. Rosenman, Pyroelectric effect in KTiOPO4 and family crystals with monodomain and domain patterned structures, J PHYS D, 33(16), 2000, pp. 2069-2073
The pyroelectric effect was studied in KTiOPO4 and isomorphic ferroelectric
crystals in a wide temperature range including the transition region from
a superionic state to a dielectric state. The developed method of pyroelect
ric current monitoring has allowed the fabrication of various periodic and
quasi-periodic ferroelectric domain configurations of high quality in KTiOA
sO4, KTiOPO4, RbTiOAsO4 and RbTiOPO4 crystals for diverse nonlinear optical
converters.
