Abstract
PbTiO3 thin films on the Si substrates were prepared by plasma enhanced chemical vapor deposition (PECVD) using Ti(O‐i‐C3H7)4, Pb(C2H5)4, and oxygen. The composition of PECVD PbTiO3 thin films was intensively influenced by the input flow rate ratio of precursors while it was independent of the deposition temperatures. As‐deposited PECVD PbTiO3 thin film showed a uniform distribution of the Pb, Ti, and C component throughout the bulk of film. When an annealing process was performed at 750 °C under the O2 ambient for 1 h, the Pb/(Pb+Ti) ratio of thin films was reduced from 0.567 to 0.509.Keywords
