I-Sapphire njengesiseko sesekethe se-semiconductor
Iiwafers ezincinci zesafire zaziyindlela yokuqala ephumeleleyo yokusebenzisa i-insulating substrate apho i-silicon yayifakwa khona ukwenza iisekethe ezidibeneyo ezibizwa ngokuba yi-silicon on safire (SOS). Ukongeza kwiimpawu zayo ezintle zokufakelwa kombane, i-safire ine-thermal conductivity ephezulu. Iitships ze-CMOS kwisafire zifanelekile ngokukodwa kwizicelo zerediyo enamandla aphezulu (RF) ezifana neefowuni eziphathwayo, iirediyo zokhuseleko loluntu kunye neenkqubo zonxibelelwano lwesathelayithi.
Iiwafer zesafire eziziikristale enye zikwasetyenziswa njengezinto ezisetyenziswa kwishishini le-semiconductor lokukhulisa izixhobo ezisekelwe kwi-gallium nitride (GaN). Ukusetyenziswa kwesafire kunciphisa kakhulu iindleko njengoko ixabiso le-germanium limalunga ne-1/7th. I-GaN kwisafire isetyenziswa kakhulu kwii-diodes ezikhupha ukukhanya okuluhlaza okwesibhakabhaka (ii-LED).
Sebenzisa njengezinto zefestile
I-sapphire eyenziweyo (ngamanye amaxesha ibizwa ngokuba yiglasi ye-sapphire) idla ngokusetyenziswa njengezinto zefestile kuba ikhanya kakhulu phakathi kwe-150 nm (ultraviolet) kunye ne-5500 nm (infrared) wavelengths yokukhanya (i-spectrum ebonakalayo isusela malunga ne-380 nm ukuya kwi-750 nm) kwaye inokumelana okukhulu kakhulu nokukrwela. Iingenelo eziphambili zeefestile ze-sapphire
Bandakanya
I-bandwidth yokudlulisa i-optical ebanzi kakhulu, ukusuka kwi-UV ukuya ekukhanyeni okukufutshane ne-infrared
Inamandla kunezinye izinto ezibonakalayo okanye iifestile zeglasi
Iyamelana kakhulu nokukrweleka nokurhawuzelelwa (ubulukhuni beeminerali obuyi-9 kwisikali seMohs, ilandela idayimani kunye ne-moissanite phakathi kwezinto zendalo)
Iqondo lokunyibilika eliphezulu kakhulu (2030°C)
