Amakristalu e-GSGG
I-GGG/SGGG/NGG Garnets isetshenziselwa i-epitaxy ewuketshezi.I-SGGG subatrates iyi-substrates ezinikele yefilimu ye-magneto-optical.Ezisetshenziswa zokuxhumana ezibonakalayo, zidinga kakhulu ukusebenzisa i-1.3u kanye ne-1.5u optical isolator, ingxenye yayo eyinhloko yifilimu ye-YIG noma ye-BIG. ibekwe endaweni kazibuthe.
I-SGGG substrate inhle kakhulu ekukhuliseni amafilimu e-epitaxial e-bismuth-iron garnet yensimbi, iyinto enhle ye-YIG, BiYIG, GdBIG.
Kuhle ngokomzimba kanye nemishini kanye nokuzinza kwamakhemikhali.
Izicelo:
I-YIG, ifilimu enkulu ye-epitaxy;
Imishini ye-microwave;
Faka esikhundleni i-GGG
