Mgo Substrate txhais
MgO, luv luv rau magnesium oxide, yog ib qho siv lead ua substrate feem ntau siv nyob rau hauv daim ntawv ntawm nyias zaj duab xis deposition thiab epitaxial loj hlob.Nws muaj cov qauv siv lead ua cubic thiab zoo heev siv lead ua zoo, ua rau nws zoo tagnrho rau kev loj hlob zoo nyias zaj duab xis.
MgO substrates paub txog lawv qhov chaw du, muaj tshuaj lom neeg ruaj khov, thiab qhov tsis xws luag.Cov khoom no ua rau lawv zoo tagnrho rau cov ntawv thov xws li cov khoom siv hluav taws xob semiconductor, cov ntaub ntawv kaw lus sib nqus, thiab cov khoom siv optoelectronic.
Nyob rau hauv nyias zaj duab xis deposition, MgO substrates muab cov qauv rau kev loj hlob ntawm ntau yam ntaub ntawv xws li hlau, semiconductors thiab oxides.Cov siv lead ua kev taw qhia ntawm MgO substrate tuaj yeem ua tib zoo xaiv kom haum rau cov yeeb yaj kiab epitaxial uas xav tau, ua kom ntseeg tau qib siab ntawm cov siv lead ua kom sib haum thiab txo qis lattice mismatch.
Tsis tas li ntawd, MgO substrates yog siv rau hauv cov ntaub ntawv sib nqus vim lawv lub peev xwm los muab cov qauv siv lead ua zoo heev.Qhov no tso cai rau kom muaj txiaj ntsig zoo ntawm kev sib nqus ntawm cov khoom sib nqus hauv cov ntaub ntawv nruab nrab, ua rau cov ntaub ntawv khaws cia zoo dua.
Hauv kev xaus, MgO ib leeg substrates yog cov zoo crystalline substrates siv los ua cov qauv rau kev loj hlob ntawm epitaxial ntawm nyias zaj duab xis hauv ntau daim ntawv thov, suav nrog cov khoom siv hluav taws xob, optoelectronics, thiab cov ntaub ntawv sib nqus.
