摘要：

The Ba1-xPbxTi0.91(Hf0.5, Zr0.5)0.09O3 (x = 0, 0.03) thin films on Nb-doped SrTiO3 (100) and (111) substrates were synthesized by the pulsed laser deposition method using fourth harmonic generated light (γ = 266 nm) of Nd3+:YAG laser beam. The peaks of the pyroelectric coefficient of BaTi0.91(Hf0.5, Zr0.5)0.09O3 thin film on Nb doped SrTiO3 (111) were observed at 85.6°C, 100.8°C and 103.6°C. The cross-sectional images of the this thin film on Nb doped SrTiO3 (100) substrate were observed by high resolution transmission electron microscopy. The X-ray diffraction measurements at room temperature of the Ba0.97Pb0.03Ti0.91 (Hf0.5,Zr0.5)0.09O3 thin film on the Nb-doped SrTiO3(100) substrate were carried out, and it showed [100]/[001] preference orientation with satellite peaks. This thin film on the Nb-doped SrTiO3 (111) substrate exhibited ferroelectric properties.
