dc.description.abstract | The ferroelectric phase transition of three single crystals of TGSe1−x DTGSex has been described
by using specific heat, latent heat, and dielectric permittivity measurements. Pure, half-deuterated,
and highly-deuterated TGSe single crystals were analyzed. Transition temperature and latent heat
increase with increasing deuteration. Irrespective of the degree of deuteration, a 2-4-6 Landau model
is suitable to describe the phase transition. The fourth-rank prefactor in Landau potential is found to
be very sensitive to deuteration while the second-rank and the sixth-rank prefactors smoothly
change with composition. The pyroelectric figure of merit for these materials has also been derived
from the theoretical model. | es |
