I-GGG Substrate
Incazelo
I-Gallium Gadolinium Garnet (Gd3Ga5O12noma i-GGG) i-single crystal iyinto enezinto ezinhle zokubuka, ezomshini nezokushisa eziyenza ithembise ukusetshenziswa ekwenziweni kwezingxenye ezihlukahlukene ze-optical kanye ne-substrate material yamafilimu e-magneto-optical kanye nama-high-temperature superconductors. i-infrared optical isolator (1.3 kanye ne-1.5um), okuyidivayisi ebaluleke kakhulu ekuxhumaneni kokubona.Yenziwe ngefilimu ye-YIG noma ye-BIG ku-substrate ye-GGG kanye nezingxenye ze-birefringence.Futhi i-GGG iyi-substrate ebalulekile ye-microwave isolator namanye amadivaysi.Izakhiwo zayo ezingokomzimba, zemishini kanye namakhemikhali zonke zilungele lezi zinhlelo zokusebenza ezingenhla.

Incazelo ye-GGG Substrate
I-GGG substrate isho i-substrate eyenziwe nge-gadolinium gallium garnet (GGG) crystal material.I-GGG iyinhlanganisela yekristalu yokwenziwa ehlanganiswe izakhi ze-gadolinium (Gd), i-gallium (Ga) kanye nomoya-mpilo (O).
Ama-substrates e-GGG asetshenziswa kakhulu kumadivayisi we-magneto-optical kanye nama-spintronics ngenxa yezindawo zawo ezinhle kakhulu kazibuthe nezokubonwayo.Ezinye izici ezibalulekile ze-GGG substrates zifaka:
1. Ukukhanya okuphezulu okuphezulu: I-GGG inobubanzi obuhlukahlukene bokudluliswa kwe-infrared (IR) kanye ne-spectrum yokukhanya ebonakalayo, efanele ukusetshenziswa kokubona.
2. Izici ze-Magneto-optical: I-GGG ibonisa imiphumela eqinile ye-magneto-optical, efana nomphumela we-Faraday, lapho ukuhlukaniswa kokukhanya okudlula ezintweni kuzungezisa ngokuphendula inkambu kazibuthe esetshenzisiwe.Lesi sakhiwo sivumela ukuthuthukiswa kwamadivayisi ahlukahlukene we-magneto-optical, afaka ama-isolator, ama-modulators, nezinzwa.
3. Ukuzinza okuphezulu kwe-thermal: I-GGG inokusimama okuphezulu kokushisa, okuyenza ikwazi ukumelana nokucutshungulwa kwezinga lokushisa ngaphandle kokuwohloka okukhulu.
4. Ukunwetshwa kwe-thermal okuphansi: I-GGG ine-coefficient ephansi yokunwetshwa kwe-thermal, okuyenza ihambisane nezinye izinto ezisetshenziswa ekwenziweni kwedivayisi nokunciphisa ingozi yokwehluleka ngenxa yengcindezi yemishini.
Ama-substrates e-GGG avame ukusetshenziswa njengama-substrates noma izendlalelo ze-buffer zokukhula kwamafilimu amancane noma izakhiwo ze-multilayer kumadivayisi we-magneto-optical kanye ne-spintronic.Angasetshenziswa futhi njengezisetshenziswa ze-Faraday rotator noma izakhi ezisebenzayo kuma-lasers namadivayisi angashintshisani.
Lawa ma-substrates ngokuvamile akhiqizwa kusetshenziswa amasu ahlukahlukene okukhula kwekristalu njenge-Czochralski, i-flux noma amasu okusabela okuqinile kwesimo.Indlela ethize esetshenzisiwe incike kwikhwalithi ye-substrate ye-GGG efunwayo nosayizi.
