LGS Substrate
Fa'amatalaga
E mafai ona fa'aoga LGS e fai ai masini piezoelectric ma electro-optical.E maualuga le vevela o mea piezoelectric.O le coefficient so'otaga eletise e tolu taimi o le quartz, ma o le vevela o le suiga o vaega e maualuga (mai le vevela o le potu i le mea liusuavai 1470 ℃).E mafai ona faʻaaogaina i le vaʻai, BAW, maualuga le vevela vevela ma le malosi maualuga, maualuga le toe faia o le eletise-optic Q-sui.

LGS Substrate Fa'amatalaga
LGS (Lithium Gallium Silicate) substrate e fa'atatau i se ituaiga o mea fa'apipi'i e masani ona fa'aaogaina mo le fa'atupulaia o ata manifinifi tioata tasi.LGS substrates e masani ona faʻaaogaina i fanua o masini eletise-optic ma acousto-optic, e pei o le faʻaliliuina o taimi, faʻaogaina o mea faʻapipiʻi, masini galu acoustic, ma isi.
LGS substrates e aofia ai lithium, gallium, ma silicate ions ma fausaga tioata patino.O lenei tu'ufa'atasiga tu'ufa'atasi e tu'uina atu ai le LGS substrates lelei fa'apitoa ma mea fa'aletino mo fa'aoga eseese.O nei mea'ai e fa'aalia ai fa'ailoga mata'utia maualuga, maualalo le malamalama, ma le manino lelei i le va'aiga lata mai-infrared le umi galu.
LGS substrates e sili ona talafeagai mo le tuputupu aʻe o fausaga ata manifinifi ona e fetaui ma auala eseese o le teuina e pei ole molecular beam epitaxy (MBE) poʻo le epitaxial growth method e pei ole chemical vapor deposition (CVD).
O meatotino fa'apitoa o mea'ai a le LGS, e pei o piezoelectric ma mea fa'aeletise-optic, e fa'aigoa lelei mo masini gaosi e mana'omia ai mea fa'apipi'i e pulea le voluma po'o le fa'atupuina o galu acoustic.
I se aotelega, LGS substrates o se ituaiga maʻoti o mea faʻapipiʻi e faʻaaogaina e faʻatupu ai ata manifinifi tioata tasi mo faʻaoga i masini eletise-optic ma acousto-optic.O nei substrates o loʻo i ai mea faʻapitoa faʻapitoa ma mea faʻapitoa e faʻaogaina ai mo le tele o faʻaoga faʻaogaina ma eletise.
