Lithium Niobate (LN) siv lead ua muaj siab spontaneous polarization (0.70 C / m² nyob rau hauv chav tsev kub) thiab yog ib tug ferroelectric siv lead ua uas siab tshaj Curie kub (1210 ℃) pom tam sim no. LN Crystal muaj ob tus yam ntxwv uas nyiam cov xim tshwj xeeb. Ua ntej, nws muaj ntau yam super photoelectric los, nrog rau cov nyhuv piezoelectric, electro-optic nyhuv, nonlinear optical nyhuv, photorefractive nyhuv, photovoltaic nyhuv, photoelastic nyhuv, acoustooptic nyhuv thiab lwm yam photoelectric zog. Qhov thib ob, kev ua tau zoo ntawm LN siv lead ua yog kho tau zoo heev, uas yog tshwm sim los ntawm cov qauv lattice thiab ntau yam tsis xws luag ntawm LN siv lead ua. Ntau yam khoom ntawm LN siv lead ua tuaj yeem tswj tau zoo los ntawm cov khoom siv lead ua, cov khoom siv doping, valence xeev tswj thiab lwm yam. Tsis tas li ntawd, LN siv lead ua yog nplua nuj nyob rau hauv raw cov ntaub ntawv, uas txhais tau hais tias high-zoo thiab loj-loj siv lead ua ib qho yooj yim los npaj.

Lub LN siv lead ua muaj qhov ruaj khov ntawm lub cev thiab tshuaj lom neeg, yooj yim rau kev ua, dav lub teeb kis tau tus mob (0.3 ~ 5μm), thiab muaj ib tug loj birefringence (txog 0.8 @ 633 nm), thiab yooj yim los ua rau hauv high-zoo optical waveguide. Yog li ntawd, LN-raws li optoelectronic li, xws li nto acoustic yoj lim, lub teeb modulator, theem modulator, optical isolator, electro-optic Q-hloov (www.wisoptic.com), yog dav kawm thiab siv rau cov nram qab no teb: electronics technology. , optical kev sib txuas lus technology, laser technology. Tsis ntev los no, nrog rau kev ua tiav hauv daim ntawv thov ntawm 5G, micro / nano photonics, kev sib koom ua ke ntawm photonics thiab quantum optics, LN crystals tau nyiam dav dua. Hauv 2017, Burrows ntawm Harvard University txawm hais tias lub sijhawm ntawm“lithium niobate hav” tam sim no los.
