Kurzbeschreibung (Abstract)

In the present work, the pyroelectric properties of Sn-doped BaTiO3 (BaTi1-xSnxO3)were investigated. A significant increase in pyroelectric coefficient was observed for x = 0.05 composition and found to be 10 x 10-4 C/m2 K at 350 K. Further, the pyroelectric figure of merits (FOMs) for current responsivity (Fi), voltage responsivity(Fv), and energy harvesting (Fe and F*e ) were calculated for all investigated samples. A large improvement in FOMs was achieved for x = 0.05 compared with undoped ceramic. BaTi1-xSnxO3 (x = 0.05) was subjected to further pyroelectric analysis revealing an open-circuit voltage of 0.6 V when it was exposed to temporal temperature gradient. The voltage and current were also measured across resistances 100 kΩ, 1 MΩ, and 5 MΩ. The results reveal that BaTi0.95Sn0.05O3 will be one of the potential lead-free pyroelectric materials.
