Safiro nk'igice cy'urukiramende cya semiconductor
Udupira duto twa safiro ni two twakoreshejwe bwa mbere neza mu gukora icyuma gikingira ubushyuhe aho silikoni yashyizwe kugira ngo ikore imiyoboro y’amashanyarazi yitwa silikoni kuri safiro (SOS). Uretse ubushobozi bwayo bwiza bwo gukingira ubushyuhe, safiro ifite ubushobozi bwo gutwara ubushyuhe bwinshi. Udupira twa CMOS kuri safiro tubereye cyane cyane mu gukoresha radiyo ifite imbaraga nyinshi (RF) nka telefoni zigendanwa, radiyo z’umutekano rusange na sisitemu z’itumanaho rya satelite.
Uduce twa safiro twitwa crystal wafers natwo dukoreshwa nk'ibikoresho bya semiconductor mu guhinga ibikoresho bishingiye kuri gallium nitride (GaN). Gukoresha safiro bigabanya cyane ikiguzi kuko ari hafi 1/7 cy'igiciro cya germanium. GaN kuri safiro ikoreshwa cyane mu byuma bisohora urumuri rw'ubururu (LEDs).
Koresha nk'ibikoresho byo mu idirishya
Sapphire y’ubukorikori (rimwe na rimwe yitwa ikirahure cya Sapphire) ikunze gukoreshwa nk'ibikoresho by'idirishya kuko ibonerana cyane hagati ya nm 150 (ultraviolet) na nm 5500 (infrared) z'urumuri (spectrum igaragara iri hagati ya nm 380 na 750) kandi irwanya cyane gushwanyagurika. Ibyiza by'ingenzi by'amadirishya ya Sapphire
Shyiramo
Uburyo bwo kohereza amakuru bw'urumuri rwagutse cyane, kuva kuri UV kugeza kuri infrared light
Ikomeye kurusha ibindi bikoresho by'urumuri cyangwa amadirishya y'ibirahuri
Irwanya cyane gushwanyaguza no gushwanyagurika (ubukomere bw'amabuye y'agaciro bwa 9 ku gipimo cya Mohs, ikaba iya kabiri nyuma ya diyama na moissanite mu bintu bisanzwe)
Ahantu hashyuha cyane (2030°C)
Ishusho irambuye
