Black Lithium Niobate Wafer - China
price: contact company for price
Free-pyro black LiNbO3 and LiTaO3 wafers were prepared successfully by chemical reduction under a mixed atmosphere of CO2 and H2 - Bulk conductivity and optical transmittance of the black LiNbO3 and black LiTaO3 wafers were measured.
The results showed that the pyroelectric effect for the reduced wafers was almost eliminated and the transmittance decreased considerably.
The reduction process did not change Curie temperatures or piezoelectric properties of LN and LT wafers, while neutralize electrical charges even if the electrical potential occurs instantaneously.
The reduction technology is used to produce Black Lithium Niobate (LiNbO3) which has high ability to neutralize electrical charges even if the electrical potential occurs instantaneously.
Black Lithium Niobate shows no difference in piezoelectric properties from standard wafers.
As a result, black reduced lithium niobate wafers are widely adopted to produce higher frequency SAW devices.
