Gawo la SrTiO3
Kufotokozera
SrTiO3 single crystal ili ndi mawonekedwe abwino a lattice a perovskite structure material.Ndi gawo laling'ono labwino kwambiri la kukula kwa epitaxy kwa HTS ndi mafilimu ambiri a oxide.Zakhala zikugwiritsidwa ntchito kwambiri pofufuza za kutentha kwapamwamba kwa mafilimu owonda kwambiri a superconducting.Amagwiritsidwanso ntchito kwambiri m'mazenera apadera owoneka bwino komanso zolinga zapamwamba za sputtering.

SrTiO3 Substrate Tanthauzo
Gawo laling'ono la SrTiO3 limatanthawuza gawo lapansi la crystalline lopangidwa ndi strontium titanate (SrTiO3).SrTiO3 ndi zinthu za perovskite zomwe zimakhala ndi cubic crystal structure, yomwe imadziwika ndi dielectric nthawi zonse, kutentha kwakukulu kwa kutentha, komanso kugwirizanitsa bwino kwa latisi ndi zipangizo zina zambiri.
Magawo a SrTiO3 amagwiritsidwa ntchito kwambiri m'magawo a filimu yopyapyala komanso kukula kwa epitaxial.Kapangidwe ka kiyubiki ka SrTiO3 kumathandizira kukula kwa makanema owonda apamwamba kwambiri okhala ndi kristalo wabwino kwambiri komanso kusachulukira kochepa.Izi zimapangitsa magawo a SrTiO3 kukhala abwino kwambiri pakukulitsa mafilimu a epitaxial ndi ma heterostructures pazogwiritsa ntchito zosiyanasiyana.
Kukhazikika kwa dielectric kwa SrTiO3 kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito monga ma capacitor, zida zamakumbukiro, ndi makanema owonda kwambiri a ferroelectric.Kukhazikika kwake kwa kutentha kumapangitsa kuti ikhale yoyenera kugwiritsira ntchito kutentha kwakukulu.
Kuphatikiza apo, zinthu zosiyanasiyana za SrTiO3, monga kupangika kwake kwachitsulo pamatenthedwe otsika komanso kuthekera kopangitsa kuti dziko likhale labwino kwambiri, zimapangitsa kuti zikhale zothandiza pakufufuza kwafizikiki yazinthu komanso kupanga zida zamagetsi ndi optoelectronic.
Mwachidule, magawo a SrTiO3 ndi ma crystalline substrates opangidwa ndi strontium titanate, omwe amagwiritsidwa ntchito kwambiri poyika filimu yopyapyala, kukula kwa epitaxial, ndi ntchito zosiyanasiyana zamagetsi ndi optoelectronic chifukwa cha kuchuluka kwawo kwa dielectric nthawi zonse, kukhazikika kwamafuta, komanso zinthu zabwino zofananira ndi lattice.
