I-MgO Substrate
Incazelo
I-MgO single substrate ingasetshenziswa ukwakha umshini wokuxhumana weselula odingekayo kuzihlungi ze-microwave ezinezinga eliphezulu lokushisa eliphezulu kanye namanye amadivaysi.
Sisebenzise ukupholishwa kwekhemikhali okungase kulungiselelwe izinga eliphezulu le-athomu ebusweni bomkhiqizo, Usayizi omkhulu 2”x 2”x0.5mm substrate etholakalayo.

Incazelo ye-Mgo Substrate
I-MgO, ifushane nge-magnesium oxide, iyingxenye yekristalu eyodwa evame ukusetshenziswa emkhakheni wokubekwa kwefilimu elincanyana kanye nokukhula kwe-epitaxial.Inokwakheka kwekristalu eyi-cubic kanye nekhwalithi enhle kakhulu yekristalu, okuyenza ilungele ukukhulisa amafilimu amancanyana ekhwalithi ephezulu.
Ama-MgO substrates aziwa ngokubukeka kwawo okubushelelezi, ukuqina kwamakhemikhali aphezulu, nokuminyana okungamaphutha.Lezi zakhiwo zizenza zilungele izinhlelo zokusebenza ezifana namadivayisi we-semiconductor, imidiya yokurekhoda kazibuthe, namadivayisi we-optoelectronic.
Ekufakweni kwefilimu emincane, ama-substrates e-MgO ahlinzeka ngezifanekiso zokukhula kwezinto ezihlukahlukene ezihlanganisa izinsimbi, ama-semiconductors nama-oxides.I-crystal orientation ye-substrate ye-MgO ingakhethwa ngokucophelela ukuze ifane nefilimu ye-epitaxial efiswayo, kuqinisekiswe izinga eliphezulu lokuqondanisa kwekristalu kanye nokunciphisa ukungafani kwe-lattice.
Ngaphezu kwalokho, ama-substrates e-MgO asetshenziswa kumidiya yokurekhoda kazibuthe ngenxa yekhono lazo lokuhlinzeka ngesakhiwo sekristalu esi-ode kakhulu.Lokhu kuvumela ukuqondanisa okusebenzayo kwezizinda kazibuthe endaweni yokurekhoda, okuholela ekusebenzeni okungcono kokugcinwa kwedatha.
Sengiphetha, ama-substrates e-MgO single angama-crystalline substrates ekhwalithi ephezulu asetshenziswa njengezifanekiso zokukhula kwe-epitaxial yamafilimu azacile ezinhlelweni ezihlukene, okuhlanganisa ama-semiconductors, ama-optoelectronics, nemidiya yokuqopha kazibuthe.
