GGG Substrate
Inkcazo
IGallium Gadolinium Garnet (Gd3Ga5O12okanye GGG) ikristale enye iyinto ebambekayo, esebenza ngoomatshini kunye neepropathi ezishushu ezenza ukuba ithembise ukusetyenziswa ekwenziweni kwamacandelo ahlukeneyo abonayo kunye nesubstrate imathiriyeli yeefilimu zemagneto-optical kunye nobushushu obuphezulu. i-infrared optical isolator (i-1.3 kunye ne-1.5um), eyona sixhobo esibaluleke kakhulu kunxibelelwano lwamehlo.Yenziwe ngefilimu ye-YIG okanye ye-BIG kwi-substrate ye-GGG kunye neendawo ezidibanisa i-birefringence.Kwakhona i-GGG yinxalenye ebalulekileyo ye-microwave isolator kunye nezinye izixhobo.Iimpawu zayo zomzimba, oomatshini kunye neekhemikhali zonke zilungile kwezi zicelo zingentla.

GGG Substrate Inkcazo
I-substrate ye-GGG ibhekisa kwi-substrate eyenziwe nge-gadolinium gallium garnet (GGG) imathiriyeli yekristale.I-GGG yi-synthetic crystalline compound eyenziwe yi-elementi i-gadolinium (Gd), i-gallium (i-Ga) kunye ne-oxygen (O).
Ii-substrates ze-GGG zisetyenziswa ngokubanzi kwizixhobo zemagneto-optical kunye ne-spintronics ngenxa yeempawu zazo ezibalaseleyo zemagneti kunye ne-optical.Ezinye iimpawu eziphambili zeGGG substrates ziquka:
1. Ukucaca okuphezulu: I-GGG inoluhlu olubanzi lokudluliselwa kwi-infrared (IR) kunye ne-spectrum yokukhanya ebonakalayo, efanelekileyo kwizicelo ze-optical.
2. Iimpawu zeMagneto-optical: I-GGG ibonisa iziphumo ezinamandla zemagneto-optical, ezifana ne-Faraday effect, apho i-polarization yokukhanya okudlula kwizinto ezijikelezayo ngokuphendula kwintsimi yamagnetic esetyenzisiweyo.Le propathi yenza ukuba kuphuhliswe izixhobo ezahlukeneyo zemagneto-optical, kubandakanya i-isolator, iimodyuli kunye nezinzwa.
3. Ukuzinza okuphezulu kwe-thermal: I-GGG inozinzo oluphezulu lwe-thermal, eyenza ukuba ikwazi ukumelana nokulungiswa kweqondo lokushisa ngaphandle kokuthotywa okukhulu.
4. Ukwandiswa kwe-thermal ephantsi: I-GGG ine-coefficient ephantsi yokwandiswa kwe-thermal, eyenza ihambelane nezinye izinto ezisetyenziselwa ukuveliswa kwesixhobo kunye nokunciphisa umngcipheko wokungaphumeleli ngenxa yoxinzelelo lomatshini.
Iisubstrates zeGGG ziqhele ukusetyenziswa njenge substrates okanye buffer layers ekukhuleni kweefilim ezibhityileyo okanye izakhiwo zemultilayer kwimagneto-optical and spintronic devices.Zingaphinda zisetyenziswe njengezinto ezijikelezayo zeFaraday okanye izinto ezisebenzayo kwiilaser kunye nezixhobo ezingezizo.
Ezi substrates zihlala ziveliswa kusetyenziswa iindlela ezahlukeneyo zokukhula kwekristale ezifana neCzochralski, i-flux okanye iindlela zokusabela eziqinileyo.Indlela ethile esetyenzisiweyo ixhomekeke kumgangatho ofunekayo we-GGG substrate kunye nobukhulu.
