| Abstract: | Preparation of Si-based ferroelectric thin films with excellent properties is important to the fabrication of Si-based single chip UFPA device. Si-based (Pb 1- x Sr x )TiO 3(PST) ferroelectric thin films were prepared successfully by magnetron sputtering in this paper. The PST thin films were compatible with the Si microelectronics in the preparation process. The LSCO/ITO and the Au films were used as the base electrode and the top electrode of the PST thin films, respectively. The microstructure of the PST thin films was compact and the resistance ratio of the PST thin films was 10 11 Ω·cm order. Its dielectric constant and pyroelectric coefficient were 10 2 and 10 -2 μC/cm 2K order, respectively. |
