Ikristale yeLithium niobate yeyona nto ibalaseleyo yepiezoelectric eneezi mpawu zilandelayo:ubushushu obuphezulu beCurie, i-coefficient yobushushu obuphantsi besiphumo se-piezoelectric, i-electromechanical coefficient coupling coefficient, ilahleko ephantsi ye-dielectric, iipropati ezizinzileyo zomzimba kunye neekhemikhali, ukusebenza kakuhle kokusebenza, kunye nokulula ukulungiselela ubungakanani obukhulu kunye nekristale ephezulu.Xa kuthelekiswa ne-piezoelectric crystal quartz esetyenziswa ngokuqhelekileyo,LNikristaleinophezuluisantya sesandingenxaukulungiswa kwamacandelo aphezulu, ngoko kunokusetyenziswaukwenzairesonator, itransducer, umgca wokulibazisa, isihluzi, njl.. ezisetyenziswa kakhulu ethandwa kwiindawo abahlaliunxibelelwano oluphathwayo, unxibelelwano ngesathelayithi, ukusetyenzwa komqondiso wedijithali, iTV, unomathotholo, irada, iremote sensing,kunye neendawo zomkhosi zombaneamanyathelo okuthintela, i-fuze, isikhokelo,njl..

Eyona ngokubanziukusetyenziswa kwekristale LNsisihluzo sokucoca amaza omphezulu (SAWF).Ukusukela ngeminyaka yee-1970,i-midfrequency SAWF eyenziwe kwi-LNIkristale isetyenziswe ngokubanzi kwiiseti zikamabonwakude ezinemibala, iifowuni ezingenazintambo, ulawulo olukude lwe-elektroniki, njl.njl. Ngo-2010, kunye nokusetyenziswa kwe-silicon tuner edibeneyo ye-chips, ukuba izihluzo zamaza zomphezulu kwiiseti ze-TV ziye zarhoxiswa ngokusisiseko kwimarike.SUkusukela ngo-1980, unxibelelwano oluphathwayo lutshintshile ukusuka kwi-2G ukuya kwi-5G, kwaye i-terminal yeselula kufuneka ihambelane ngasemva,ezi zize aukunyuka kwemfunoSAWF. Ukuba each frequency band imfunosizihluzi ezimbini, ifowuni nganyeintandokufuneka ngaphezulu kwekhuluSAWF. Menye yeii-SAWF zenziwe nge-LN orlithium tantaliiikristale. Ikristale ye-LN ithandwa kakhulu kwizixhobo ze-SAWF ngeimbuyekezo lobushushuuyilo (TCSAW).

Ukusetyenziswa kwe-piezoelectric, ukubunjwa kweLNIkristale inefuthe elikhulu kwisantya sesandi, kwaye uluhlu lwayo lokuguquguquka kufuneka lulawulwe ngokungqongqo. Bngenxa yobushushu beCurie bunovakalelo kakhulu kukwakheka kwekristale, keitihlala isetyenziselwa ukubonakalisa ukuhambelana kokwakheka kwekristale.Ukongezelela, i-domain eyodwa ye-crystal iya kuchaphazela ngokuthe ngqoyayoiimpawu ze-piezoelectric.Tke ngoko,isitixoiteknolojiiinkcukacha ze-ical yeekristale ze-LN ezisetyenziswe kwipheizixhobo iezoelectric kubandakanywaeubushushu beCurie,imimandla yemonopole,kunye namasuntswana okusasaza ngaphakathi,njl .. Kwikristale, aboiliza lomatshinis ezinobude obude azikhathaleliI-lattice inezipheneezizi kwisikaliincinci kakhulu kunobude bobude. Iikristale ze-LN ezihlangabezana nemfuneko yepiezoelectricizicelo ziebizwa ngokuba “yi-acousticibakala LNikristale”.

Indlela yokusika yebakala le-acousticLNikristale inxulumeneyayoisicelo esithile.Ukusika kwe-Y-axisLNI-crystal ine-coefficient ephezulu yokudibanisa i-electromechanical, kodwaineencinciisicelo ngenxa yochulumanco olugqithisileyo lwamaza omamkeli.I-<1014> i-crystal yokusika ine-excitation ye-wave wave encinci kwaye isetyenziswa ngokubanzi(I-TCSAW ngomnye wemizekelo). Kwindlela yoku<1014>, Y-ekseniiyajikelezangokuchasene newotshi 127.86° ajikeleza i X-ekseni.Ezi crystals ze-LNeqhele ukubizwa ngokuba yi-128°YLNikristale.Ukwengeza,LNikristales nge-engile yokusika64°Y kunye ne-41°Yziifaneleke ngakumbi ukulungiselela iimveliso zamaxesha amaninzi.Ngoku,ubungakanani bepiezoelectricIkristale ye-LNifikelele kwi-intshi ezi-6.

Ukongeza, uLewis wachaza impembelelo ye-pyroelectric effectLNIkristale ekulungiseleleni izixhobo zamaza e-acoustic emhlabeni ngo-1982, kwaye yafumanisa ukuba isiphumo se-pyroelectricLNIkristale ikhokelela ekutshatyalalisweni kwe-electrode kunye nekristale, enokuthi icinezelwe ngokusebenzisa indlela yokumelana nentsimbi ye-short-circuit electrode.Ngowe-1998, uStandifer et al.yamkela indlela yonyango lokunciphisa imichiza ukwandisa ukufunxa ukukhanyaLNI-crystal ngamaxesha e-1000, ukuphucula umgangatho wokuvezwa kwemigca emincinci kunye neyona nto ibhetele ngexesha le-photolithography, kunye nokwandisa i-crystal '.sconductivity ngaphezu1×10⁵ amaxesha.Le ndlelaukubambasumonakalo we-electrode yomnwe womnqamlezosokubangelwa yimpembelelo ye-pyroelectric kwinkqubo yonyango lokushisaiizixhobo zamaza acoustic ngaphezulu.ILNI-wafer elungiselelwe yile ndlela ibizwa ngokuba "mnyama LN”leyoisetyenziswe ngokubanzi kwiSAWF.

Iikristale ezikumgangatho ophezulu ze-LN eziveliswe kwindlu ye-WISOPTIC (www.wiseptic.com)
