DESCRIPTION:Pyroelectric materials convert fluctuating heat flows to elect
 rical energy. The most efficient pyroelectric materials are inorganic ferr
 oelectrics\, that is\, materials showing spontaneous\, switchable electric
  polarization. We have developed a computational methodology to study the 
 atomic-level mechanisms of pyroelectricity in inorganic ferroelectrics. We
  determine the primary pyroelectric coefficients by combining hybrid densi
 ty functional calculations with self-consistent phonon theory and the Berr
 y phase approach for polarization. Secondary pyroelectric coefficients are
  evaluated by combining thermal properties from quasi-harmonic approximati
 on with elastic and piezoelectric coefficients.
