    Sapphire Boule (Single-Crystal Al₂O₃) — Ibibazo Bikunze Kubazwa

    Q1: Imbuto ya safiro ni iki?
    A: Ikirisitu imwe ya oksidi ya aluminiyumu (Al₂O₃) imaze guhingwa. Ni "ingot" yo hejuru ikoreshwa mu gukora utubati twa safiro, amadirishya y'urumuri, n'ibikoresho byambara cyane.

    Q2: Ni gute umupira w'imbwa ufitanye isano na wafer cyangwa amadirishya?
    A: Imbuto irazunguruka → iciwemo uduce duto → iraseye neza kugira ngo ikoremo utubuto twa epi-grade cyangwa ibice by'ingufu. Ubusa bw'imbuto ikomokaho bigira ingaruka zikomeye ku musaruro wo hasi.

    Q3: Ni ubuhe buryo bwo gukura buhari kandi butandukanye bute?
    A: KY (Kyropoulos)naHEMumusaruro munini,stress nkeyaboules—zikundwa cyane mu gukoresha epitaxy na optique yo mu rwego rwo hejuru.CZ (Czochralski)itanga umusaruro mwiza cyanekugenzura icyerekezono guhuza ibintu byinshi.Verneuil (urumuri-ihuriro) is ihendutseku byuma rusange by'urumuri n'amabuye y'agaciro.

    Q4: Ni ibihe byerekezo utanga? Ni ubuhe buryo busanzwe bwo gukora neza?
    A: c-plane (0001), a-plane (11-20), r-plane (1-102), m-plane (10-10), n'imigenzo. Ubusanzwe icyerekezo gihamye≤ ± 0.1°byemejwe na Laue/XRD (birushijeho kuba bibi iyo ubisabye).

  • Ibanjirije iyi:

    • Amabuye y'agaciro yo mu rwego rwa Optical hamwe n'imicungire myiza y'ibisigazwa by'ibikoresho byo mu nzu

    Boule zacu zose za safiro zikorwa kugira ngourwego rw'amaso, kwemeza ko ubushobozi bwo kohereza ibintu buri hejuru, guhuza neza, no kuba nta bushobozi bwo gushyiramo/gusohora ibintu cyangwa kwimura ibintu ku buryo bukabije kuri optique na electronics. Dugenzura icyerekezo cya kristale n'uburyo bwo gukurura ibintu biva ku mbuto ujya ku zindi, hamwe n'uburyo bwo gukurikirana ibintu byose no guhuza uburyo binyuramo. Ingano, icyerekezo (c-, a-, r-plane), n'uburyo bwo kwihanganira ibintu bishobora guhindurwa hakurikijwe ibyo ukeneye mu gukata/gusukura.
    Icy'ingenzi ni uko ibikoresho byose bitajyanye n'ibisobanuro byabyo aribyatunganyijwe byose mu nzubinyuze mu buryo bwo gukora ibintu buri mu nzira ifunze—gutondeka, kongera gukoreshwa, no gutabwa mu buryo bukwiye—kugira ngo ubone ubuziranenge bwizewe nta guhangana cyangwa ngo ukurikize amategeko. Ubu buryo bugabanya ibyago, bugabanya igihe cyo gukora, kandi bugashyigikira intego zawe zo kubungabunga ibidukikije.
