Abstract:

      La and Mn doped PbTiO3 films are prepared by gel route sol method and heat treated at 700c for 1 hr. Pyrocurrent of films are studied by using ho me made temperature controller and nanoammeter. Pyroelectric coefficients of the sample are also examined. For charge storage mechanism, C-2 – V characteristic were also studied.

Key words: Pyroelectric current, pyroelectric coefficient and 1 –V characteristics c2
