Black Lithium Niobate Wafers

Lithium niobate wafers are renowned for their use in surface acoustic wave (SAW) devices, such as SAW filters, which benefit from their low insertion loss. However, these crystals' optical transparency and pyroelectric effects can present challenges during processing and application. Black lithium niobate wafers offer an effective solution to these issues. Black lithium niobate wafers can be produced through a chemical reduction process in a mixed atmosphere of CO₂ and H₂. The obtained lithium niobate wafer has a high ability to neutralize charges rapidly, even when there is an instantaneous potential. Consequently, the pyroelectric effect in black lithium niobate wafers is largely eliminated, and the optical transmittance is considerably reduced. Despite these changes, the piezoelectric properties of black lithium niobate wafers remain comparable to those of standard lithium niobate wafers. In a word, the black lithium niobate wafers' ability to mitigate issues related to optical transparency and pyroelectric effects, without compromising its piezoelectric performance, makes it highly suitable for various high-frequency SAW device applications.
