Sesebelisoa sa MgAl2O4
Tlhaloso
Magnesium aluminate (MgAl2O4) likristale tse le 'ngoe li sebelisoa haholo lisebelisoa tsa sonic le microwave le li-epitaxial MgAl2O4 substrates tsa lisebelisoa tsa III-V nitride.Khalase ea MgAl2O4 e kile ea e-ba thata ho hōla hobane ho thata ho boloka sebopeho sa eona sa kristale se le seng.Empa hajoale re khonne ho fana ka likristale tsa boleng bo holimo tsa 2 inch diameter MgAl2O4.

Tlhaloso ea MgAl2O4 Substrate
MgAl2O4 substrate e bua ka mofuta o khethehileng oa substrate e entsoeng ka motsoako oa magnesium aluminate (MgAl2O4).Ke thepa ea ceramic e nang le thepa e 'maloa e lakatsehang bakeng sa lits'ebetso tse fapaneng.
MgAl2O4, e tsejoang hape e le spinel, ke ntho e thata e hlakileng e nang le botsitso bo phahameng ba mocheso, lik'hemik'hale tse hanyetsanang le matla a mochine.Mehaho ena e etsa hore e loketse ho sebelisoa e le substrate liindasteri tse fapa-fapaneng, ho kenyelletsa le lisebelisoa tsa elektronike, optics le aerospace.
Lefapheng la lisebelisoa tsa elektroniki, li-substrates tsa MgAl2O4 li ka sebelisoa e le sethala sa ho holisa lifilimi tse tšesaane le likarolo tsa epitaxial tsa li-semiconductors kapa lisebelisoa tse ling tsa elektroniki.Sena se ka etsa hore ho be le lisebelisoa tsa elektroniki tse kang transistors, li-circuits tse kopaneng le li-sensor.
Ho optics, li-substrates tsa MgAl2O4 li ka sebelisoa bakeng sa ho beha likhahla tse tšesaane tsa filimi ho ntlafatsa ts'ebetso le ho tšoarella ha likarolo tsa optical joalo ka lilense, li-filters le liipone.Ponaletso ea substrate ho pholletsa le mefuta e mengata ea wavelengths e etsa hore e tšoanelehe ka ho khetheha bakeng sa lits'ebetso tse libakeng tsa ultraviolet (UV), tse bonahalang, le tse haufi le infrared (NIR).
Lefapheng la lifofane, li-substrates tsa MgAl2O4 li sebelisoa bakeng sa conductivity ea tsona e phahameng ea mocheso le ho hanyetsa mocheso oa mocheso.Li sebelisoa e le litene tsa ho haha lisebelisoa tsa elektronike, litsamaiso tsa tšireletso ea mocheso le thepa ea mohaho.
Ka kakaretso, li-substrates tsa MgAl2O4 li na le motsoako oa lisebelisoa tsa optical, thermal, le mechine tse etsang hore li be le thuso lits'ebetsong tse fapaneng, ho kenyeletsoa indasteri ea lisebelisoa tsa elektroniki, tsa optics le tsa aerospace.
