GGG Substrate
Tsanangudzo
Gallium Gadolinium Garnet (Gd3Ga5O12kana GGG) single crystal chinhu chine yakanaka optical, mechanic and thermal properties izvo zvinoita kuti ivimbise kushandiswa mukugadzirwa kwezvinhu zvakasiyana-siyana zvemaziso pamwe ne substrate material yemagneto-optical films uye high-temperature superconductors.Ndiyo yakanakisa substrate material infrared optical isolator (1.3 uye 1.5um), inova mudziyo wakakosha mukukurukurirana kwemaziso.Yakagadzirwa neYIG kana BIG firimu paGGG substrate pamwe nebirefringence zvikamu.Zvakare GGG yakakosha substrate ye microwave isolator uye zvimwe zvishandiso.Yayo yemuviri, yemagetsi uye makemikari zvimiro zvese zvakanaka kune zviri pamusoro apa maapplication.

GGG Substrate Tsanangudzo
GGG substrate inoreva substrate yakagadzirwa ne gadolinium gallium garnet (GGG) crystal material.GGG inhengo yekristalline yakagadzirwa inoumbwa nezvinhu gadolinium (Gd), gallium (Ga) uye okisijeni (O).
GGG substrates inoshandiswa zvakanyanya mumagineti-optical zvishandiso uye spintronics nekuda kweakanakisa magineti uye optical zvivakwa.Zvimwe zvakakosha zveGGG substrates zvinosanganisira:
1. Kujeka kwepamusoro: GGG ine huwandu hwakawanda hwekutumira mu infrared (IR) uye inooneka chiedza chechiedza, inokodzera kushandiswa kwemaziso.
2. Magneto-optical properties: GGG inoratidzira yakasimba magneto-optical effects, yakadai seFaraday effect, umo polarization yechiedza inopfuura nepakati pezvinhu inotenderera ichipindura kune inoshandiswa magnetic field.Ichi chivakwa chinogonesa kuvandudzwa kweakasiyana magneto-optical zvishandiso, zvinosanganisira isolators, modulators, uye sensors.
3. High thermal stability: GGG ine high thermal stability, iyo inoita kuti ikwanise kumira kupisa kwekushisa kwepamusoro pasina kukanganisa kukuru.
4. Kuwedzera kwekuwedzera kwekushisa: GGG ine chidimbu chakaderera chekuwedzera kwekushisa, zvichiita kuti ienderane nezvimwe zvinhu zvinoshandiswa mukugadzirwa kwechigadzirwa uye kuderedza dambudziko rekukundikana nekuda kwekunetseka kwemagetsi.
GGG substrates anowanzo shandiswa se substrates kana buffer layers pakukura kwemafirimu matete kana multilayer zvimiro mumagneto-optical uye spintronic zvishandiso.Iwo anogona zvakare kushandiswa seFaraday rotator zvinhu kana zvinhu zvinoshanda mumalaser uye zvisingadzoreki zvishandiso.
Aya ma substrates anowanzo gadzirwa uchishandisa akasiyana makristasi ekukura matekiniki akadai seCzochralski, flux kana yakasimba mamiriro ekuita maitiro.Iyo chaiyo nzira inoshandiswa zvinoenderana neinodiwa GGG substrate mhando uye saizi.
