LGS Substrate
Kev piav qhia
LGS tuaj yeem siv los ua piezoelectric thiab electro-optical li.Nws muaj qhov kub thiab txias piezoelectric zog.Lub electromechanical coupling coefficient yog peb zaug ntawm cov quartz, thiab cov theem hloov pauv kub yog siab (los ntawm chav tsev kub mus rau melting point 1470 ℃).Nws tuaj yeem siv rau hauv kev pom, BAW, kub sensor thiab siab zog, siab rov ua dua tus nqi electro-optic Q-hloov.

LGS Substrate txhais
LGS (Lithium Gallium Silicate) substrate yog hais txog ib yam ntawm cov khoom siv substrate uas feem ntau siv rau kev loj hlob ntawm ib leeg siv lead ua nyias zaj duab xis.LGS substrates yog siv nyob rau hauv cov teb ntawm electro-optic thiab acousto-optic li, xws li zaus converters, kho qhov muag modulators, nto acoustic yoj pab kiag li lawm, thiab lwm yam.
LGS substrates muaj lithium, gallium, thiab silicate ions nrog cov qauv siv lead ua tshwj xeeb.Qhov tshwj xeeb muaj pes tsawg leeg no muab LGS substrates zoo tagnrho kho qhov muag thiab lub cev muaj zog rau ntau yam kev siv.Cov substrates no nthuav tawm qhov ntsuas qhov ntsuas siab siab, tsis tshua muaj lub teeb pom kev zoo, thiab cov pob tshab zoo heev hauv qhov pom ntawm ze-infrared wavelength ntau yam.
LGS substrates yog tshwj xeeb tshaj yog haum rau kev loj hlob ntawm nyias zaj duab xis qauv raws li lawv tau sib xws nrog ntau yam kev tso nyiaj xws li molecular beam epitaxy (MBE) los yog epitaxial txoj kev loj hlob xws li tshuaj vapor deposition (CVD).
Cov khoom tshwj xeeb ntawm LGS substrates, xws li piezoelectric thiab electro-optic zog, ua rau lawv zoo tagnrho rau kev tsim cov khoom siv uas yuav tsum tau muaj cov khoom siv hluav taws xob tswj hluav taws xob lossis tsim cov acoustic vuag.
Hauv cov ntsiab lus, LGS substrates yog ib hom khoom siv substrate siv los loj hlob ib leeg-crystal nyias zaj duab xis rau kev siv hauv cov khoom siv electro-optic thiab acousto-optic.Cov substrates no muaj cov khoom siv kho qhov muag thiab lub cev xav tau uas ua rau lawv haum rau ntau yam kev siv kho qhov muag thiab hluav taws xob.
