GGG Substrate
Ibisobanuro
Gallium Gadolinium Garnet (Gd3Ga5O12cyangwa GGG) kristu imwe ni ibikoresho bifite optique nziza, ubukanishi nubushyuhe butuma itanga ikizere cyo gukoresha muguhimba ibice bitandukanye bya optique kimwe nibikoresho bya substrate ya firime ya magneto-optique hamwe nubushyuhe bwo hejuru cyane.Ni ibikoresho byiza bya substrate kuri infrared optique isolator (1.3 na 1.5um), nigikoresho cyingenzi mugutumanaho kwa optique.Ikozwe muri YIG cyangwa BIG firime kuri GGG substrate wongeyeho ibice bya birefringence.Na none GGG ni substrate yingenzi ya microwave isolator nibindi bikoresho.Imiterere yumubiri, ubukanishi nubumashini nibyiza byose mubisabwa haruguru.

Ibisobanuro bya GGG
GGG substrate bivuga substrate ikozwe muri gadolinium gallium garnet (GGG) ibikoresho bya kristu.GGG ni intungamubiri ya kristaline igizwe nibintu gadolinium (Gd), gallium (Ga) na ogisijeni (O).
GGG substrates ikoreshwa cyane mubikoresho bya magneto-optique hamwe na spintronics bitewe nibyiza bya magnetiki na optique.Bimwe mubintu byingenzi biranga GGG substrates harimo:
1. Gukorera mu mucyo mwinshi: GGG ifite uburyo bwinshi bwo kohereza muri infragre (IR) hamwe n’umucyo ugaragara, ubereye porogaramu nziza.
2. Imiterere ya Magneto-optique: GGG yerekana imbaraga zikomeye za magneto-optique, nkingaruka ya Faraday, aho polarisiyasi yumucyo inyura mubintu bisimburana hasubijwe umurima wa rukuruzi.Uyu mutungo ushoboza iterambere ryibikoresho bitandukanye bya magneto-optique, harimo kwigunga, modulator, hamwe na sensor.
3. Ubushyuhe bukabije bwo hejuru: GGG ifite ubushyuhe buhanitse, butuma ishobora guhangana nubushyuhe bwo hejuru butangirika cyane.
4. Kwiyongera k'ubushyuhe buke: GGG ifite coefficient nkeya yo kwagura ubushyuhe, bigatuma ihuza nibindi bikoresho bikoreshwa muguhimba ibikoresho no kugabanya ibyago byo gutsindwa kubera guhangayika.
GGG isanzwe ikoreshwa nka substrate cyangwa buffer kugirango ikure ya firime yoroheje cyangwa inyubako nyinshi mubikoresho bya magneto-optique na spintronic.Birashobora kandi gukoreshwa nkibikoresho bya rotate ya Faraday cyangwa ibintu bikora muri laseri nibikoresho bidahwitse.
Ubusanzwe insimburangingo ikorwa hifashishijwe uburyo butandukanye bwo gukura bwa kristu nka Czochralski, flux cyangwa tekinike ikomeye ya reta.Uburyo bwihariye bwakoreshejwe buterwa na GGG substrate yifuzwa nubunini.
