4inch 6inch Lithium niobate filimi e le 'ngoe ea kristale ea LNOI

Tlhaloso e Khutšoanyane:

Lithium niobate e na le lisebelisoa tse ntle haholo tsa electro-optical, nonlinear le piezoelectric. Ka thuso ea theknoloji e tsoetseng pele ea ho sebetsana le li-micro le nano, lisebelisoa tse kopantsoeng tsa photonics tse thehiloeng ho lithium niobate thin films (LNOI) ho li-insulators li 'nile tsa ntlafatsoa haholo. Nakong e tlang, lisebelisoa tsa LNOI tse sebetsang hantle li tla tšehetsa tsoelo-pele e tsoelang pele ea LNOI-based micro-nano optics, photonics e kopantsoeng, le microwave photonics. Tlhahiso ea lisebelisoa tse phahameng tsa LNOI e tla ba mohato oa bohlokoa ts'ebetsong ea indasteri ea lisebelisoa tsa lithium niobate optoelectronics.

1- Lifilimi tsa Lithium niobate piezoelectric (LNOI) li na le coefficient e phahameng ea piezoelectric le dielectric constant, tse ka fetolelang matla a mochini hore e be matla a motlakase kapa matla a motlakase hore e be matla a mochini. Ka hona, e sebelisoa haholo lefapheng la li-sensor, tse kang li-sensor tsa khatello, li-acceleration sensors, lisebelisoa tsa mocheso joalo-joalo. Ho feta moo, filimi ea lithium niobate piezoelectric e ka boela ea sebelisoa lisebelisoa tsa acoustic le lisebelisoa tsa vibration, tse kang piezoelectric ceramic transducer complex piezoelectric ceramic filter.

2-Ho tsitsa ha filimi ea lithium niobate piezoelectric le eona ke e 'ngoe ea melemo ea eona. Ka lebaka la botsitso ba sebopeho sa kristale le ho se sebetse ha lik'hemik'hale, filimi ea lithium niobate piezoelectric e ka sebetsa ka mocheso o phahameng, mongobo o phahameng, acid e matla, alkali e matla le tikoloho e 'ngoe e thata, e nang le ho hanyetsa kutu le ho tšoarella hantle.

Filimi ea 3-Lithium niobate piezoelectric ke thepa e ncha ea piezoelectric e nang le ts'ebetso e ntle haholo le botsitso, 'me e na le tebello e pharaletseng ea ts'ebeliso. Ka nts'etsopele e tsoelang pele ea mahlale le thekenoloji, filimi ea lithium niobate piezoelectric e tla sebelisoa metseng e mengata, e tlisang boiketlo le boqapi bo eketsehileng bophelong ba batho.
