LiTaO3 Substrate Definition
I-LiTaO3 (i-lithium tantalate) i-substrate ibhekiselele kwi-crystalline imathiriyeli edla ngokusetyenziswa kwizicelo ezahlukeneyo ze-elektroniki kunye ne-optoelectronic.Nanga amanye amanqaku aphambili malunga neLiTaO3 substrates:
1. Isakhiwo se-Crystal: I-LiTaO3 ine-crystal structure ye-perovskite, ebonakaliswe yi-network-dimensional network ye-athomu ye-oxygen apho i-lithium kunye ne-athomu ye-tantalum ithatha izikhundla ezithile.
2. Iimpawu ze-Piezoelectric: I-LiTaO3 i-piezoelectric ephezulu, oku kuthetha ukuba ivelisa intlawulo yombane xa iphantsi koxinzelelo lomatshini kunye nokunye.Eli nqaku liyenza ibe luncedo kwizixhobo ezahlukeneyo zamaza e-acoustic ezifana ne-surface acoustic wave (SAW) izihluzi kunye neeresonators.
3. Iimpawu ze-optical nonlinear: I-LiTaO3 ibonisa iimpawu ezinamandla ezingabonakaliyo ezingabonakaliyo, ezivumela ukuba zivelise ama-frequencies amatsha okanye ukuguqula iimpawu zokukhanya kwesiganeko ngokusebenzisa intsebenziswano engabonakaliyo.Ngokuqhelekileyo isetyenziswa kwizixhobo ezisebenzisa isizukulwana sesibini se-harmonic (SHG) okanye i-optical parametric oscillation (OPO), njengeekristale eziphindwe kabini okanye iimodyuli zamehlo.
4. Uluhlu olubanzi lokungafihli: I-LiTaO3 inoluhlu olubanzi lokungafihli ukusuka kwi-ultraviolet (UV) ukuya kummandla we-infrared (IR).Iyakwazi ukuhambisa ukukhanya ukusuka malunga ne-0.38 μm ukuya kwi-5.5 μm, iyenza ifaneleke kwiinkqubo ezahlukeneyo ze-optoelectronic ezisebenza kolu luhlu.
5. Ubushushu obuphezulu beCurie: I-LiTaO3 inokushisa okuphezulu kweCurie (Tc) malunga ne-610 ° C, iqondo lokushisa apho iipropathi zayo ze-piezoelectric kunye ne-ferroelectric ziyanyamalala.Oku kuyenza ilungele izicelo zobushushu obuphezulu obunje ngezixhobo zamaza amaza omsindo aphezulu okanye izinzwa zobushushu obuphezulu.
6. Ukuzinza kweekhemikhali: I-LiTaO3 iqinile kwaye ixhatshazwa kwii-solvents eziqhelekileyo kunye ne-acids.Olu uzinzo luqinisekisa ukuqina kunye nokuthembeka kwe-substrate kwiimeko ezahlukeneyo zokusebenza kunye neendawo.
7. Iimpawu ezilungileyo zoomatshini kunye ne-thermal: I-LiTaO3 inamandla omatshini kunye nokuzinza kwe-thermal, eyenza ukuba ikwazi ukumelana noxinzelelo lomatshini kunye nokushisa okuphezulu ngaphandle kokuguqulwa okukhulu okanye ukuthotywa.Oku kuyenza ilungele izicelo eziphezulu zamandla okanye iindawo ezinomatshini obunzima okanye iimeko ezishushu.
I-substrates ye-LiTaO3 isetyenziswa ngokubanzi kwizicelo ezahlukeneyo ezibandakanya izixhobo ze-SAW, izixhobo zokuphindaphinda kabini, iimodyuli zamehlo, i-optical waveguides, njl.njl. Indibaniselwano yayo yeepropathi ze-piezoelectric kunye ne-nonlinear optical, uluhlu olubanzi lokungafihli, ubushushu obuphezulu beCurie, ukuzinza kweekhemikhali, kunye nomatshini olungileyo kunye ne-thermal. iipropathi ziyenza ibe yimathiriyeli eguquguqukayo kwicandelo le-elektroniki kunye ne-optoelectronics.
