Sesebelisoa sa Kholiso sa Sapphire Ingot Mokhoa oa Czochralski CZ oa ho Hlahisa Li-wafer tsa Sapphire tsa lisenthimithara tse 2-12

Tlhaloso e Khutšoanyane:

Sesebelisoa sa Kholiso sa Sapphire Ingot (Mokhoa oa Czochralski)ke sistimi ea sejoale-joale e etselitsoeng kholo ea kristale e le 'ngoe ea safire e hloekileng haholo, e se nang sekoli se tlase. Mokhoa oa Czochralski (CZ) o nolofalletsa taolo e nepahetseng ea lebelo la ho hula kristale ea peo (0.5–5 mm/h), sekhahla sa ho potoloha (5–30 rpm), le maemo a mocheso ka har'a sebopi sa iridium, e hlahisang likristale tse lekanang le bophara ba lisenthimithara tse 300. Sesebelisoa sena se tšehetsa taolo ea tataiso ea kristale ea C/A-plane, e nolofalletsang kholo ea optical-grade, electronic-grade, le doped safire (mohlala, Cr³⁺ ruby, Ti³⁺ star safire).

XKH e fana ka ditharollo tsa ho tloha qalong ho isa qetellong, ho kenyeletswa le ho fetola disebediswa (tlhahiso ya wafer ya di-inch tse 2–12), ntlafatso ya tshebetso (bongata ba sekoli <100/cm²), le thupelo ya botekgeniki, ka tlhahiso ya kgwedi le kgwedi ya di-wafer tse fetang 5,000 bakeng sa ditshebediso tse kang di-substrate tsa LED, GaN epitaxy, le diphutheloana tsa semiconductor.
