LiNbO3 Substrate Tlhaloso:
LiNbO3 (lithium niobate) substrate e bua ka thepa ea kristale eo hangata e sebelisoang e le substrate kapa substrate lisebelisoa tse fapaneng tsa elektroniki le optoelectronic.Mona ke lintlha tsa bohlokoa mabapi le li-substrates tsa LiNbO3:
1. Sebopeho sa kristale: LiNbO3 ke kristale ea ferroelectric e nang le mohaho oa perovskite.E na le liathomo tsa lithium (Li) le niobium (Nb) tse hlophisitsoeng ka lesela le khethehileng la kristale.
2. Lintho tsa Piezoelectric: LiNbO3 e na le thepa e matla ea piezoelectric, e bolelang hore e hlahisa litefiso tsa motlakase ha e le tlas'a khatello ea mochine le ka tsela e fapaneng.Thepa ena e etsa hore e tšoanelehe bakeng sa lits'ebetso tse joalo ka lisebelisoa tsa maqhubu a acoustic, li-sensor, li-actuator, jj.
3. Lintho tsa photoelectric: LiNbO3 e boetse e na le lisebelisoa tse ntle haholo tsa optical le electro-optic.E na le index e phahameng ea refractive, ho monya leseli le tlase, 'me e bonts'a ketsahalo e tsejoang ka hore ke electro-optic effect, moo index ea eona ea refractive e ka fetoloang ke lebala la motlakase le kantle.Mehaho ena e etsa hore e be ea bohlokoa lits'ebetsong tse kang optical modulators, waveguides, frequency double, le tse ling.
4. Phapang e pharaletseng ea ho pepeseha: LiNbO3 e na le mefuta e mengata e hlakileng, e lumellang hore e fetise leseli ka mokhoa o bonahalang le o haufi le infrared spectrum.E ka sebelisoa ho etsa lisebelisoa tsa optical tse sebetsang libakeng tsena tsa wavelength.
5. Khōlo ea kristale le mokhoa oa ho itloaetsa: Likristale tsa LiNbO3 li ka hōlileng ka ho sebelisa mekhoa e sa tšoaneng e kang Czochralski le mekhoa ea ho hōlisa tharollo ea top-seeded.E ka khaola le ho shebana le litsela tse fapaneng tsa crystallographic ho fumana thepa e khethehileng ea optical le ea motlakase e hlokahalang bakeng sa ho etsa lisebelisoa.
6. Botsitso bo phahameng ba mechine le lik'hemik'hale: LiNbO3 e tsitsitse ka mochine le lik'hemik'hale, e e nolofalletsang ho mamella.
