Sharaxaad Gaaban:

LiNbO3 Ingot (Lithium Niobate Crystal Ingot) waa shay ka samaysan optoelectronics horumarsan iyo tignoolajiyada tirada, caan ku ah isku xidhka elektro-optic-ga gaarka ah (γ₃₃= 30.9 pm/V), daah-furnaan ballaaran (400-5,200 nm), iyo heerkul sare oo Curie (1210 ° C). Si ka duwan agabka silikon-ku-salaysan ee caadiga ah, LiNbO3 ingots waxa ay awood u siinaysaa farsamaynta calaamadaha soo noqnoqda ee soo noqnoqota iyo samaynta hagaha mowjadaha waaweyn, taas oo ka dhigaysa lama huraan u ah isgaadhsiinta 5G/6G, sawirada quantum photonics, iyo dareenka warshadaha. Horumarkii u dambeeyay ee is dhexgalka kala duwan (tusaale, waferrada isku dhafan ee ku salaysan Si-ku-salaysan) iyo yaraynta cilladaha (tusaale, Mg doping) ayaa sii balaadhiyey ku-dhaqanka deegaanka xad-dhaafka ah, sida heerkulka sare (> 400°C) dareemayaasha iyo nidaamyada hawada sare ee shucaaca adag.
