GGG substrate txhais
GGG substrate yog hais txog lub substrate ua los ntawm gadolinium gallium garnet (GGG) siv lead ua khoom.GGG yog ib qho hluavtaws crystalline compound uas muaj cov ntsiab lus gadolinium (Gd), gallium (Ga) thiab oxygen (O).
GGG substrates tau dav siv hauv cov khoom siv magneto-optical thiab spintronics vim lawv cov khoom sib nqus zoo heev thiab kho qhov muag.Qee cov khoom tseem ceeb ntawm GGG substrates suav nrog:
1. High transparency: GGG muaj ntau yam kis tau tus mob nyob rau hauv infrared (IR) thiab pom lub teeb spectrum, haum rau optical daim ntaub ntawv.
2. Magneto-optical zog: GGG nthuav tawm muaj zog magneto-optical teebmeem, xws li cov nyhuv Faraday, nyob rau hauv uas lub polarization ntawm lub teeb dhau los ntawm cov khoom rotates teb rau ib daim ntawv thov magnetic teb.Cov cuab yeej no tso cai rau kev txhim kho ntau yam khoom siv magneto-optical, suav nrog kev cais tawm, kev hloov pauv, thiab cov sensors.
3. High thermal stability: GGG muaj thermal stability siab, uas ua rau nws tuaj yeem tiv taus kub ua haujlwm yam tsis muaj kev puas tsuaj loj.
4. Tsawg thermal expansion: GGG muaj cov coefficient qis ntawm thermal expansion, ua rau nws sib xws nrog lwm cov ntaub ntawv siv hauv kev tsim cov cuab yeej thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav vim kev ntxhov siab ntawm cov tshuab.
GGG substrates feem ntau yog siv los ua cov substrates lossis tsis txheej rau kev loj hlob ntawm cov yeeb yaj kiab nyias lossis ntau txheej txheej hauv cov khoom siv magneto-optical thiab spintronic.Lawv tuaj yeem siv los ua Faraday rotator cov ntaub ntawv lossis cov khoom siv hauv lasers thiab cov khoom siv tsis sib xws.
Cov substrates no feem ntau yog tsim los siv ntau yam siv lead ua kev loj hlob xws li Czochralski, flux los yog cov txheej txheem hauv lub xeev cov tshuaj tiv thaiv.Txoj kev siv tshwj xeeb yog nyob ntawm qhov xav tau GGG substrate zoo thiab loj.
