Litiyumu Niobate (LN) kristu ifite polarisiyonike yo hejuru (0,70 C / m)2 ku bushyuhe bwicyumba) kandi ni kristu ya ferroelectric hamwe nubushyuhe bwo hejuru bwa Curie (1210 ℃) byabonetse kugeza ubu. LN kristu ifite ibintu bibiri bikurura ibitekerezo byihariye. Ubwa mbere, ifite ingaruka nyinshi zamafoto yumuriro, harimo ingaruka za piezoelectric, ingaruka ya electro-optique, ingaruka zidafite umurongo wa optique, ingaruka zifotora, ingaruka zifotora, ingaruka zifotora, ingaruka za acoustooptic nibindi bintu bifotora. Icya kabiri, imikorere ya LN kristu irashobora guhindurwa cyane, iterwa nuburyo bwa lattice hamwe nubusembwa bwinshi bwa LN kristu. Ibintu byinshi bya LN kristu irashobora kugengwa cyane na kristaliste, element doping, valence leta igenzura nibindi. Mubyongeyeho, kristu ya LN ikungahaye ku bikoresho fatizo, bivuze ko bifite ireme-binini kandi binini cyane kristaliste byoroshye kuyitegura.
LN ya kirisiti ifite imiterere ihamye yumubiri na chimique, byoroshye gutunganya, urumuri rwagutse (0.3 ~ 5μm), kandi ifite birefringence nini (hafi 0.8 @ 633 nm), kandi byoroshye gukora muburyo bwiza bwo guhitamo optique. Kubwibyo, ibikoresho bya LN bishingiye kuri optoelectronic, urugero hejuru ya acoustic wave filter, modulator yumucyo, moderi ya moderi, optique ya optique, electro-optique Q-switch (www.wisoptic.com), yizwe cyane kandi ikoreshwa mubice bikurikira: ikoranabuhanga rya elegitoroniki , tekinoroji yo gutumanaho optique, tekinoroji ya laser. Vuba aha, hamwe nibyagezweho mugukoresha 5G, micro / nano Photonics, guhuza fotonike hamwe na kwant optique, kristu ya LN yongeye gukurura abantu benshi. Muri 2017, Burrows yo muri kaminuza ya Harvard ndetse yasabye ko ibihe bya“ikibaya cya niobate” ubu iraza.
