SrTiO3 Substrate txhais
SrTiO3 substrate yog hais txog cov crystalline substrate ua los ntawm cov compound strontium titanate (SrTiO3).SrTiO3 yog cov khoom siv perovskite nrog lub cubic siv lead ua qauv, uas yog tus cwj pwm los ntawm lub siab dielectric tas li, siab thermal stability, thiab zoo lattice txuam nrog ntau lwm cov ntaub ntawv.
SrTiO3 substrates yog dav siv nyob rau hauv cov teb ntawm nyias zaj duab xis deposition thiab epitaxial loj hlob.Cov qauv cubic ntawm SrTiO3 tso cai rau kev loj hlob ntawm cov yeeb yaj kiab zoo tshaj plaws nrog cov crystalline zoo thiab qhov tsis xws luag.Qhov no ua rau SrTiO3 substrates zoo heev rau kev loj hlob epitaxial films thiab heterostructures rau ntau yam kev siv.
Lub siab dielectric tas li ntawm SrTiO3 ua rau nws tsim nyog rau daim ntaub ntawv xws li capacitors, nco li, thiab ferroelectric nyias films.Nws thermal stability ua rau nws haum rau cov ntawv thov kub.
Tsis tas li ntawd, cov khoom sib txawv ntawm SrTiO3, xws li nws cov xim hlau conductivity ntawm qhov kub thiab txias thiab muaj peev xwm ntawm inducing lub xeev superconducting, ua rau nws pab tau rau condensed teeb meem physics tshawb fawb thiab kev loj hlob ntawm hluav taws xob thiab optoelectronic li.
Nyob rau hauv cov ntsiab lus, SrTiO3 substrates yog crystalline substrates ua los ntawm strontium titanate, uas yog feem ntau siv nyob rau hauv nyias zaj duab xis deposition, epitaxial loj hlob, thiab ib tug ntau yam ntawm hluav taws xob thiab optoelectronic daim ntaub ntawv vim lawv siab dielectric tas li, thermal stability, thiab zoo lattice matching zog.
