Substrate GGG
Sharaxaada
Gallium Gadolinium Garnet (Gd3Ga5O12ama GGG) hal crystal waa walxo leh muuqaalo wanaagsan, farsamo iyo kulayl taas oo ka dhigaysa mid rajo u leh in loo isticmaalo samaynta qaybaha kala duwan ee indhaha iyo sidoo kale walxaha substrate ee filimada magneto-optical iyo superconductors heerkul sare. Infrared optical isolator (1.3 iyo 1.5um), oo ah aalad aad muhiim u ah isgaarsiinta indhaha.Waxay ka samaysan tahay YIG ama filim BIG ah oo ku yaal substrate GGG oo lagu daray qaybo birefringence ah.Sidoo kale GGG waa substrate muhiim u ah go'doominta microwave iyo aaladaha kale.Sifooyinkeeda jidheed, makaanikada iyo kiimikaad ayaa dhamaantood u fiican codsiyada kor ku xusan.

Qeexida Substrate-ka GGG
Substrate GGG waxa loola jeedaa substrate ka samaysan gadolinium gallium garnet (GGG) walxo crystal ah.GGG waa iskudhis crystalline synthetic oo ka kooban curiyeyaasha gadolinium (Gd), gallium (Ga) iyo ogsijiin (O).
Substrates GGG ayaa si weyn loogu isticmaalaa aaladaha magneto-optical iyo spintronics sababtoo ah sifooyinkooda magnetic iyo indhaha ee ugu fiican.Qaar ka mid ah sifooyinka muhiimka ah ee GGG substrates waxaa ka mid ah:
1. Daah-furnaan sare: GGG waxay leedahay faafin ballaaran oo kala duwan oo ah infrared (IR) iyo iftiinka iftiinka muuqda, oo ku habboon codsiyada indhaha.
2. Magneto-optical Properties: GGG waxay soo bandhigaysaa saameyn xoog leh oo magneto-optical ah, sida saamaynta Faraday, kaas oo polarization ee iftiinka dhex mara walxaha uu u wareego jawaab celinta magnetic field.Hantidani waxay awood u siinaysaa horumarinta qalabyada magneto-optical ee kala duwan, oo ay ku jiraan kuwa go'doomiya, modulators, iyo dareemayaasha.
3. Deganaanshaha kulaylka sare: GGG waxay leedahay xasillooni heerkul sare ah, taas oo u oggolaanaysa inay u adkaysato habka heerkulka sare iyada oo aan hoos u dhicin.
4. Balaadhinta kulaylka hooseeya: GGG waxay leedahay isugeyn hoose oo balaadhinta kulaylka, taas oo ka dhigaysa mid la jaan qaadaysa agabka kale ee loo isticmaalo samaynta aaladda iyo yaraynta khatarta fashilka sababtoo ah cadaadiska farsamada.
Substrate-ka GGG waxa caadi ahaan loo isticmaalaa sida substrates ama lakabyo daboolaya korriinka filimada khafiifka ah ama qaab dhismeedka lakabyada badan ee magneto-optical iyo spintronic.Waxa kale oo loo isticmaali karaa sidii qalab wareeg ah oo Faraday ah ama walxaha firfircoon ee leysarka iyo aaladaha aan is-dhaafsiga lahayn.
Substrate-yadan waxaa sida caadiga ah lagu soo saaraa iyadoo la isticmaalayo farsamooyin korriin crystal kala duwan sida Czochralski, flux ama farsamooyinka falcelinta xaalad adag.Habka gaarka ah ee loo isticmaalo waxay ku xiran tahay tayada iyo cabbirka substrate GGG ee la doonayo.
