Sharaxaad Gaaban:

Ingots-ka LiTaO₃ (Lithium Tantalate) waxay matalaan walxaha piezoelectric iyo ferroelectric-ka ee waxqabadka sare leh oo caan ku ah sifooyinka gaarka ah ee piezoelectric, xasilloonida kulaylka, iyo astaamaha indhaha, taasoo ka dhigaysa kuwo aan lagama maarmaan u ah shaandheeyayaasha hirarka acoustic-ga dusha sare (SAW), resonators-ka hirarka acoustic-ga badan (BAW), dareemayaasha infrared-ka, iyo modulators-ka indhaha. XKH waxay ku takhasustay R&D iyo soo saarista ingots-ka LiTaO₃ ee tayada sare leh, iyadoo adeegsanaysa koritaanka kiristaalka Czochralski (CZ) iyo teknoolojiyada hagaajinta stoichiometric si loo hubiyo isku-dhafka kristalka ee sare oo leh cufnaanta cilladaha <500 cm⁻².

XKH waxay bixisaa ingots LiTaO₃ dhexroorkoodu yahay 50-150mm oo leh jihooyin badan oo crystallographic ah (X-cut, Y-cut, Z-cut), oo taageeraya daaweynta doping-ka ee la habeeyey (Mg, Zn) iyo daaweynta poling-ka si loo daboolo shuruudaha kala duwan ee codsiga. Isku-dhafka piezoelectric ee walaxda (d₃₃~8 pC/N), isku-dhafka isku-xidhka elektiroonigga ah (K²~0.5%), iyo heerkulka Curie (~600°C) waxay LiTaO₃ u yihiin doorashada ugu habboon ee shaandheeyayaasha soo noqnoqda sare iyo dareemayaasha heerkulka sare.

Wax soo saarka isku dhafan wuxuu daboolaa nadiifinta walxaha ceeriin ah, kobaca kiristaalka, iyo habaynta saxda ah, wuxuu u adeegaa isgaarsiinta 5G, elektaroonigga macaamiisha, nidaamyada difaaca, iyo aaladaha photonic. Waxaan bixinaa la-talin farsamo oo dhammaystiran, tijaabin muunad ah, iyo habayn yar oo dufcad ah si loo bixiyo xalalka LiTaO₃ ee la hagaajiyay.
