Description of LiTaO3 Wafer:

Lithium tantalate (LiTaO3) has a perovskite M6 crystal structure. It has a unique combination of optical, piezoelectric, and pyroelectric properties. The applications of lithium tantalate crystal include nonlinear optics, passive infrared (IR) sensors such as motion detectors, terahertz (THz) generation and detection, and surface acoustic wave (SAW), just to name a few.

The character of LiTaO3 Wafer:

• Piezoelectric Properties: LiTaO3 is a piezoelectric material, meaning it can generate an electrical charge in response to mechanical stress and vice versa. This property makes LiTaO3 wafers valuable in various sensor and actuator applications.
• Optical Properties: LiTaO3 wafers have excellent optical transparency in the visible and near-infrared regions, making them suitable for use in optical devices such as modulators, waveguides, and optical switches.
• Acoustic Wave Devices: Due to its piezoelectric characteristics, LiTaO3 wafers are commonly used in surface acoustic wave (SAW) devices for signal processing applications.
• High Temperature Stability: LiTaO3 exhibits good thermal stability, making it suitable for applications in high-temperature environments.
• Ferroelectric Properties: LiTaO3 is a ferroelectric material, meaning it has a spontaneous electric polarization that can be reversed by the application of an external electric field. This property is utilized in various memory and sensor applications.
• Substrate for Thin Films: LiTaO3 wafers are often used as substrates for the growth of thin films for applications in integrated optics, surface acoustic wave devices, and other electronic devices.
