GGG Substrate Definition
GGG substrate yana nufin wani abu na gadolinium gallium garnet (GGG) crystal abu.GGG wani fili ne na roba wanda ya ƙunshi abubuwan gadolinium (Gd), gallium (Ga) da oxygen (O).
GGG substrates ana amfani da ko'ina a magneto-Optical na'urorin da spintronics saboda da m Magnetic da Tantancewar Properties.Wasu mahimman kaddarorin GGG sun haɗa da:
1. Babban nuna gaskiya: GGG yana da nau'i mai yawa na watsawa a cikin infrared (IR) da haske mai haske, wanda ya dace da aikace-aikacen gani.
2. Magneto-optical Properties: GGG yana nuna tasiri mai ƙarfi na magneto-optical, irin su tasirin Faraday, wanda polarization na hasken da ke wucewa ta cikin kayan yana juyawa a mayar da martani ga filin maganadisu.Wannan kadarar tana ba da damar haɓaka na'urorin magneto-optical daban-daban, gami da masu keɓancewa, modulators, da na'urori masu auna firikwensin.
3. Babban kwanciyar hankali na thermal: GGG yana da babban kwanciyar hankali na thermal, wanda ke ba shi damar yin tsayayya da sarrafa zafin jiki ba tare da raguwa mai mahimmanci ba.
.
GGG substrates yawanci ana amfani da su azaman maɓalli ko yadudduka don haɓakar fina-finai na bakin ciki ko tsarin multilayer a cikin na'urorin magneto-optical da spintronic.Hakanan za'a iya amfani da su azaman kayan rotator na Faraday ko abubuwa masu aiki a cikin na'urorin laser da na'urori marasa daidaituwa.
Ana samar da waɗannan nau'ikan nau'ikan nau'ikan nau'ikan ƙira iri-iri kamar Czochralski, juzu'i ko dabarun halayen yanayi.Takamammen hanyar da aka yi amfani da ita ya dogara da ingancin ma'aunin GGG da ake so.
