LiTaO3 Single crystal is one of the most useful substrate materials for TV-IF filters. When a SAW is propagated along the rotated 112Y direction on the X-cut plate, LiTaO3 single crystal exhibits such excellent SAW properties as low temperature coefficient of delay time, compromise coupling coefficient and low spurious level of bulk wave. In order to grow LiTaO3 crystals available for SAW devices, the growth conditions of x-axis LiTaO3 single crystals with large dimensions at low cost were...

LiTaO3 Single crystal is one of the most useful substrate materials for TV-IF filters. When a SAW is propagated along the rotated 112Y direction on the X-cut plate, LiTaO3 single crystal exhibits such excellent SAW properties as low temperature coefficient of delay time, compromise coupling coefficient and low spurious level of bulk wave. In order to grow LiTaO3 crystals available for SAW devices, the growth conditions of x-axis LiTaO3 single crystals with large dimensions at low cost were investigated by the Czochralski technigue. A large LiTaO3 single crystal with dimensions of 40-50mm in diameter, and 50-60mm in length was successfully grown using an economic Pt-Rh crucible. The elastic, piezoelectric, and dielectric constants have been determined for LiTa03 single crystals at room temperature.

X切割112°YLiTaO_3单晶是用作TV-IF滤波器的最有用的基片材料之一。为了生长供SAW器件使用的LiTaO_3单晶,用提拉法研究了大直径低成本的LiTaO_3单晶的生长条件。用廉价的Pt-Rh坩埚成功地生长出了直径40—50毫米、长50—60毫米的大的LiTaO_3单晶。测量了室温下LiTaO_3单晶的弹性、压电和介电常数。

The effects of lattice distortion and structural defects of the polycrystalline film have been taken into consideration. A polycrystalline model of ZnO piezoelectric thin film has been established to calculate the SAW velocities and effective electromechanical coupling factors of ZnO-glass and ZnO-fused quartz structure. The calculated values of the polycrystalline model fit the experimental values better than that of simple crystal model. The analysis based on the polycrystalline model also show that...

The effects of lattice distortion and structural defects of the polycrystalline film have been taken into consideration. A polycrystalline model of ZnO piezoelectric thin film has been established to calculate the SAW velocities and effective electromechanical coupling factors of ZnO-glass and ZnO-fused quartz structure. The calculated values of the polycrystalline model fit the experimental values better than that of simple crystal model. The analysis based on the polycrystalline model also show that the standard deviation of C-axis orientation has only minor influence on the SAW properties of ZnO piezoelectric film and the lattice distortion is the prime detrimental factor.
