DyScO3 Substrate Txhais
DyScO3 (dysprosium scandate) substrate yog hais txog ib yam ntawm cov khoom siv substrate feem ntau siv hauv kev loj hlob ntawm cov yeeb yaj kiab nyias thiab epitaxy.Nws yog ib qho crystal substrate nrog cov qauv siv lead ua tshwj xeeb tsim los ntawm dysprosium, scandium thiab oxygen ions.
DyScO3 substrates muaj ntau yam khoom tsim nyog uas ua rau lawv haum rau ntau yam kev siv.Cov no suav nrog cov ntsiab lus siab melting, zoo thermal stability, thiab lattice mismatch nrog ntau cov ntaub ntawv oxide, ua rau kev loj hlob ntawm cov yeeb yaj kiab zoo epitaxial nyias.
Cov substrates no yog tshwj xeeb tshaj yog haum rau loj hlob complex oxide nyias zaj duab xis uas xav tau cov khoom, xws li ferroelectric, ferromagnetic los yog high-temperature superconducting cov ntaub ntawv.Lattice mismatch ntawm substrate thiab zaj duab xis induces zaj duab xis strain, uas tswj thiab txhim khu tej yam khoom.
DyScO3 substrates feem ntau yog siv nyob rau hauv R&D lub chaw soj nstuam thiab cov chaw muaj kev lag luam kom loj hlob nyias zaj duab xis los ntawm cov tswv yim xws li pulsed laser deposition (PLD) lossis molecular beam epitaxy (MBE).Cov yeeb yaj kiab uas tau tshwm sim tuaj yeem ua tiav ntxiv thiab siv ntau yam kev siv, suav nrog cov khoom siv hluav taws xob, hluav taws xob sau, sensors thiab cov khoom siv photonic.
Hauv cov ntsiab lus, DyScO3 substrate yog ib qho siv lead ua substrate uas muaj dysprosium, scandium thiab oxygen ions.Lawv yog siv los loj hlob zoo nyias zaj duab xis nrog cov khoom tsim nyog thiab nrhiav kev siv hauv ntau yam xws li hluav taws xob, hluav taws xob thiab optics.
