Experiment

•    Sol-gel technology and the spin coating were
  emloyed. 
• Pyroelectric film - tetragonal PLZT 12/40/60
  made from metalloorganic compounds.
•   Electrodes - lanthanum-strontium cobalt oxide
  (LSCO) thin-film basing on nitrates water
  solutions.
•    Each PLZT film was set by spin-coating and
  drying during spinning. Each ten films were then
  rapid thermal processed (RTP).
•   After the RTP the PLZT film was shrinking,
  forming the separate crystallites on the LSCO
  electrode.
•    To obtain a continuous PLZT film, these
  operations were repeated ten times and then the
  films were annealed.
