Lithium niobate crystal ndi chinthu chabwino kwambiri cha piezoelectric chokhala ndizotsatirazi katundu:kutentha kwa Curie, kutentha kocheperako kwa piezoelectric effect, high electromechanical coupling coefficient, low dielectric loss, khola thupi ndi mankhwala katundu, ntchito yabwino processing, ndi zosavuta kukonzekera lalikulu kukula ndi apamwamba kristalo.Poyerekeza ndi piezoelectric crystal quartz yomwe imagwiritsidwa ntchito kwambiri,LNkristaloali apamwambaliwiro la mawuzakukonzekera zigawo zikuluzikulu pafupipafupi, kotero angagwiritsidwe ntchitokupangaresonator, transducer, mzere wochedwa, fyuluta, etc.. omwe amagwiritsidwa ntchito kwambiri m'malo a anthu wambamauthenga a m'manja, mauthenga a satellite, kukonza ma siginolo a digito, TV, wailesi, radar, zowonera kutali,ndi madera ankhondo a magetsinjira zowongolera, zowongolera, zowongolera,ndi zina..

Kwambiri kwambirikugwiritsa ntchito LN crystalndiye fyuluta yamayimbidwe apamwamba (SAWF).Kuyambira m'ma 1970,Midfrequency SAWF yopangidwa kuchokera ku LNcrystal akhala akugwiritsidwa ntchito kwambiri mu makanema TV mtundu, mafoni opanda zingwe, amazilamulira pakompyuta kutali, etc.Skuyambira zaka za m'ma 1980, kulumikizana kwa mafoni kwasintha kuchoka ku 2G kupita ku 5G, ndipo mafoni a m'manja ayenera kukhala obwerera m'mbuyo,awa anabweretsa akuchuluka kwa kufunaMtengo wa SAWF. Ngati each frequency band amafunikirasZosefera ziwiri, foni iliyonseadzateroamafuna oposa zanaMtengo wa SAWF. Mos wase SAWF amapangidwa kuchokera ku LN orlithiamu tantalindi makristasi. LN crystal ndiyodziwika kwambiri pazida za SAWF ndimalipiro a kutenthakupanga (TCSAW).

Kwa ntchito za piezoelectric, kapangidwe kakeLNcrystal imakhudza kwambiri kuthamanga kwa mawu, ndipo kusinthasintha kwake kumayenera kuyendetsedwa mosamalitsa. Bchifukwa kutentha kwa Curie kumakhudzidwa kwambiri ndi kapangidwe ka kristalo, koteroitNthawi zambiri amagwiritsidwa ntchito kuwonetsa kusasinthika kwa kristalo.Kuphatikiza apo, gawo limodzi la kristalo lidzakhudza mwachindunjizakepiezoelectric katundu.Tchifukwa chake,fungulotechnma ical specifications LN makhiristo ntchito pzipangizo za iezoelectric kuphatikizapoekutentha kwa Curie,monopole domains,ndi particles zobalalika mkati,etc.. Mu krustalo, amenewomakina mafundes okhala ndi utali wautali sakhudzidwakuwonongeka kwa latticezomwe zili mu sikelochocheperako kuposa kutalika kwa mafunde. Makristasi a LN omwe amakwaniritsa zofunikirapiezoelectricntchito ndiamatchedwa "acoustickalasi LNkristalo”.

Njira yodulira ya kalasi yamayimbidweLNkristalo imagwirizana ndizakentchito yeniyeni.Kudula kwa Y-axisLNcrystal imakhala ndi ma electromechanical coupling coefficient, komaali ndi zochepakugwiritsa ntchito chifukwa cha chisangalalo chochuluka cha wolandira mafunde.The <1014> crystal yodula imakhala ndi chisangalalo chochepa cha thupi ndipo imagwiritsidwa ntchito kwambiri(TCSAW ndi chimodzi mwa zitsanzo). Mumayendedwe a<1014>, Y-olamuliraimazungulirakutsutsana ndi 127.86°akuzungulira ndi X-olamulira.Makristalo a LN awa ndinthawi zambiri amatchedwa 128 ° YLNkristalo.Kuphatikiza apo,LNkristalos ndi ngodya yodula64°Y ndi 41°Yndiabwino kwambiri pokonzekera mankhwala okwera pafupipafupi.Panopa,kukula kwapiezoelectricChithunzi cha LNwafika 6 inchi.

Kuphatikiza apo, Lewis adanenanso za mphamvu ya pyroelectric yaLNcrystal pokonzekera zida zamtundu wamayimbidwe pamtunda mu 1982, ndipo adapeza kuti mphamvu ya pyroelectricLNkristalo kumabweretsa chiwonongeko cha elekitirodi ndi krustalo, amene akhoza kuponderezedwa pogwiritsa ntchito njira kukana mkulu zitsulo short-circuit elekitirodi.Mu 1998, Standifer et al.anatengera njira mankhwala kuchepetsa mankhwala kuonjezera mayamwidwe kuwala kwaLNkristalo ndi nthawi za 1000, sinthani mawonekedwe a mizere yopapatiza komanso yocheperako panthawi ya kujambula, ndikuwonjezera kristalo'sconductivity kuposa1× 10 pa⁵ nthawi.Njira iyiletsaskuwonongeka kwa electrode ya chala cha mtandaschifukwa cha pyroelectric mphamvu mu kutentha mankhwala ndondomeko yandipamwamba acoustic wave zida.TheLNmkate wophikidwa ndi njira iyi umatchedwa "wakuda LN”amenewakhala akugwiritsidwa ntchito kwambiri muMtengo wa SAWF.
