Sharaxaad Gaaban:

LiNbO3 Ingot (Lithium Niobate Crystal Ingot) waa walax asaasi ah oo ku jirta teknoolojiyada casriga ah ee optoelectronics iyo quantum, oo caan ku ah isku-dhafka elektiroonigga ah ee gaarka ah (γ₃₃= 30.9 pm/V), baaxadda daahfurnaanta ballaaran (400–5,200 nm), iyo heerkulka Curie sare (1210°C). Si ka duwan agabka caadiga ah ee ku salaysan silikoon, ingots-ka LiNbO3 waxay awood u siiyaan habaynta calaamadaha soo noqnoqda sare iyo soo saarista hagaha mowjadaha waaweyn, taasoo ka dhigaysa kuwo aan lagama maarmaan u ah isgaarsiinta 5G/6G, sawir-qaadista quantum, iyo dareenka warshadaha. Horumarradii ugu dambeeyay ee is-dhexgalka kala duwan (tusaale ahaan, wafers-ka isku-dhafan ee ku salaysan Si) iyo yaraynta cilladaha (tusaale ahaan, doping Mg) ayaa sii ballaariyay ku-dhaqankeeda deegaannada aadka u daran, sida dareemayaasha heerkulka sare (>400°C) iyo nidaamyada hawada sare ee shucaaca adag.
