Ferroelectric and Pyroelectric Behaviors in Poly(glycolic acid)

Dynamic pyroelectric enhancement of homogeneous ferroelectric materials

The time-dependent thermal response to a step-wise temperature increase of a ferroelectric plate of BaTiO3 of finite thickness was determined using a combination of basic heat transfer relations to model the temperature variation in the ferroelectric as a function of time and a thermodynamic model based on a modified Landau formalism to calculate the polarization profile due to the temperature ...

Pyroelectric response of ferroelectric thin films

A thermodynamic formalism is developed to calculate the pyroelectric coefficients of epitaxial ~001! Ba0.6Sr0.4TiO3 ~BST 60/40! and Pb0.5Zr0.5O3 ~PZT 50/50! thin films on ~001! LaAlO3 , 0.29 LaAlO3 :0.35(Sr2TaAlO6) ~LSAT!, MgO, Si, and SrTiO3 substrates as a function of film thickness by taking into account the formation of misfit dislocations at the growth temperature. The role of internal str...
