Tlhaloso ea GGG Substrate
GGG substrate e bolela karoloana e entsoeng ka thepa ea kristale ea gadolinium gallium garnet (GGG).GGG ke motsoako oa kristale oa maiketsetso o entsoeng ka likarolo tsa gadolinium (Gd), gallium (Ga) le oksijene (O).
Li-substrates tsa GGG li sebelisoa haholo lisebelisoa tsa magneto-optical le spintronics ka lebaka la thepa ea tsona e babatsehang ea makenete le ea mahlo.Maemo a mang a bohlokoa a likaroloana tsa GGG a kenyelletsa:
1. Ponaletso e phahameng: GGG e na le mefuta e mengata ea phetisetso ho infrared (IR) le mabone a khanyang a bonahalang, a loketseng lits'ebetso tsa optical.
2. Magneto-optical properties: GGG e bonts'a liphello tse matla tsa magneto-optical, tse kang phello ea Faraday, eo ho eona polarization ea leseli le fetang har'a thepa e potolohang ka lebaka la matla a khoheli a sebelisitsoeng.Thepa ena e thusa nts'etsopele ea lisebelisoa tse fapaneng tsa magneto-optical, ho kenyeletsoa li-isolator, li-modulator le li-sensor.
3. Botsitso bo phahameng ba mocheso: GGG e na le botsitso bo phahameng ba mocheso, e leng se etsang hore e khone ho mamella ts'ebetso e phahameng ea mocheso ntle le ho senyeha ho hoholo.
4. Katoloso e tlase ea mocheso: GGG e na le coefficient e tlase ea ho atolosoa ha mocheso, ho etsa hore e lumellane le lisebelisoa tse ling tse sebelisoang ha ho etsoa lisebelisoa le ho fokotsa kotsi ea ho hlōleha ka lebaka la khatello ea mochine.
Li-substrates tsa GGG hangata li sebelisoa e le li-substrates kapa li-buffer layers bakeng sa kholo ea lifilimi tse tšesaane kapa libopeho tse ngata ho lisebelisoa tsa magneto-optical le spintronic.Li ka sebelisoa hape e le lisebelisoa tsa rotator tsa Faraday kapa likarolo tse sebetsang ho li-lasers le lisebelisoa tse sa fetoheng.
Li-substrates tsena hangata li hlahisoa ho sebelisoa mekhoa e fapaneng ea ho holisa kristale joalo ka Czochralski, flux kapa mekhoa e tiileng ea boemo.Mokhoa o ikhethileng o sebelisoang o ipapisitse le boleng le boholo bo lakatsehang ba GGG substrate.
