Pyroelectric Precision Unleashed: Exploring the Intricacies of LiTaO3
Dive into the realm of pyroelectricity with LiTaO3, a crystalline substance renowned for its remarkable pyroelectric effect. This inherent property of LiTaO3 manifests when exposed to temperature variations, generating an electric charge that opens avenues for innovative applications. At the forefront of this technological marvel are our ultra-thin LiTaO3 wafers, a testament to precision with thicknesses as minimal as 20um at the wafer level, extending up to 4 inches in diameter. This combination of pyroelectric prowess and ultra-thin design propels LiTaO3 into the spotlight, playing a pivotal role in diverse applications, from temperature sensing in industrial settings to the creation of responsive infrared detectors.
