Incazelo emfushane:

Ama-ingots e-LiTaO₃ (Lithium Tantalate) amele izinto ezisebenza kahle ze-piezoelectric kanye ne-ferroelectric ezaziwa ngezakhiwo zazo ezihlukile ze-piezoelectric, ukuqina kwe-thermal, nezici zokubona, okuzenza zibaluleke kakhulu ezihlungini ze-surface acoustic wave (SAW), izithonjana ze-acoustic eziyinqwaba (BAW), nama-infrared modulators, nama-infrared resonators. I-XKH igxile ku-R&D kanye nokukhiqizwa kwezingothi ze-LiTaO₃ zekhwalithi ye-premium, isebenzisa ukukhula kwekristalu ye-Czochralski (CZ) kanye nobuchwepheshe bokuthuthukisa i-stoichiometric ukuze kuqinisekiswe ukufana kwekristalu okuphakeme okunokuminyana okuyisici <500 cm⁻².

I-XKH ihlinzeka ngama-LiTaO₃ ama-ingo angu-50-150mm ububanzi anomumo we-crystallographic amaningi (X-cut, Y-cut, Z-cut), esekela i-doping eyenziwe ngokwezifiso (Mg, Zn) kanye nokwelashwa kwe-poling ukuze kuhlangatshezwane nezidingo ezihlukahlukene zohlelo lokusebenza. I-piezoelectric coefficient (d₃₃~8 pC/N), i-electromechanical coefficient (K²~0.5%), nezinga lokushisa le-Curie (~600°C) lisungula i-LiTaO₃ njengenketho ekahle yezihlungi zemvamisa ephezulu nezinzwa zethempelesha ephezulu.

Ukukhiqiza okuhlanganisiwe kuhlanganisa ukuhlanzwa kwezinto ezingavuthiwe, ukukhula kwekristalu, nokucutshungulwa okunembayo, kunikeza ukuxhumana kwe-5G, izinto zikagesi zabathengi, amasistimu okuzivikela, namadivayisi ezithombe. Sihlinzeka ngokubonisana okuphelele kwezobuchwepheshe, ukuhlolwa kwesampula, nokwenza ngokwezifiso iqoqo elincane ukuletha izixazululo ze-LiTaO₃ ezithuthukisiwe.
