LiTaO3 Substrate Definition
LiTaO3 (lithium tantalate) substrate e bua ka thepa ea kristale e sebelisoang hangata lits'ebetsong tse fapaneng tsa elektroniki le tsa optoelectronic.Mona ke lintlha tsa bohlokoa mabapi le li-substrates tsa LiTaO3:
1. Sebopeho sa kristale: LiTaO3 e na le mohaho oa kristale oa perovskite, o khetholloang ke mohaho oa marang-rang a mararo a liathomo tsa oksijene tseo lithium le liathomo tsa tantalum li nang le maemo a itseng.
2. Lintho tsa Piezoelectric: LiTaO3 e na le piezoelectric e ngata, e bolelang hore e hlahisa tefiso ea motlakase ha e le tlas'a khatello ea mochine le ka tsela e fapaneng.Karolo ena e etsa hore e be molemo ho lisebelisoa tse fapaneng tsa maqhubu a acoustic wave joalo ka li-filters le li-resonator tsa sefahleho sa acoustic wave (SAW).
3. Lintho tse sa tloaelehang tsa optical: LiTaO3 e bonts'a lisebelisoa tse matla tse sa tloaelehang tsa optical, tse nolofalletsang ho hlahisa maqhubu a macha kapa ho fetola litšoaneleho tsa leseli la ketsahalo ka litšebelisano tse sa tloaelehang.E sebelisoa hangata ho lisebelisoa tse sebelisang mofuta oa bobeli oa harmonic (SHG) kapa parametric oscillation (OPO), joalo ka likristale tse habeli habeli kapa li-modulator tsa optical.
4. Phapang e pharaletseng ea ponaletso: LiTaO3 e na le mefuta e mengata ea ponaletso ho tloha ho ultraviolet (UV) ho ea sebakeng sa infrared (IR).E ka fetisa leseli ho tloha hoo e ka bang 0.38 μm ho ea ho 5.5 μm, e etsa hore e tšoanelehe bakeng sa mefuta e fapaneng ea lisebelisoa tsa optoelectronic tse sebetsang sebakeng sena.
5. Mocheso o phahameng oa Curie: LiTaO3 e na le mocheso o phahameng oa Curie (Tc) oa hoo e ka bang 610 ° C, e leng mocheso oo thepa ea eona ea piezoelectric le ferroelectric e nyamelang.Sena se etsa hore e loketse lits'ebetso tsa mocheso o phahameng joalo ka lisebelisoa tse matla tsa acoustic wave kapa li-sensor tsa mocheso o phahameng.
6. Ho tsitsa ha lik'hemik'hale: LiTaO3 e tsitsitse lik'hemik'hale 'me e hanyetsana le li-solvents le li-acids tse tloaelehileng.Botsitso bona bo tiisa ho tšoarella le ho ts'epahala ha substrate maemong a fapaneng a ts'ebetso le tikolohong.
7. Lintho tse ntle tsa mechine le tsa mocheso: LiTaO3 e na le matla a matle a mochine le botsitso ba mocheso, e leng ho e nolofalletsang ho mamella khatello ea mochine le mocheso o phahameng ntle le ho senyeha ho hoholo kapa ho senyeha.Sena se etsa hore e tšoanelehe bakeng sa lisebelisoa tse phahameng tsa matla kapa libaka tse nang le maemo a thata a mechine kapa a mocheso.
Li-substrates tsa LiTaO3 li sebelisoa haholo lits'ebetsong tse fapaneng tse kenyelletsang lisebelisoa tsa SAW, lisebelisoa tse habeli habeli, li-modulators tsa optical, li-waveguide tsa optical, joalo-joalo. thepa e etsa hore e be thepa e tenyetsehang tšimong ea elektronike le optoelectronics.
