DyScO3 Substrate Tanthauzo
DyScO3 (dysprosium scandate) gawo lapansi limatanthawuza mtundu wina wa zinthu zomwe zimagwiritsidwa ntchito pakukula kwa filimu yopyapyala ndi epitaxy.Ndi gawo limodzi la kristalo lomwe lili ndi mawonekedwe apadera a kristalo wopangidwa ndi dysprosium, scandium ndi ayoni okosijeni.
Magawo a DyScO3 ali ndi zinthu zingapo zofunika zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana.Izi zikuphatikizapo malo osungunuka kwambiri, kukhazikika kwa kutentha kwabwino, ndi kusagwirizana kwa lattice ndi zipangizo zambiri za okusayidi, zomwe zimathandiza kukula kwa mafilimu okonda kwambiri a epitaxial.
Magawo awa ndi oyenera kukulitsa mafilimu ovuta kwambiri a okusayidi okhala ndi zinthu zomwe amafunidwa, monga ferroelectric, ferromagnetic kapena kutentha kwambiri kwapamwamba kwambiri.Kusagwirizana kwa lattice pakati pa gawo lapansi ndi filimu kumapangitsa kuti filimu ikhale yovuta, yomwe imayendetsa ndi kupititsa patsogolo zinthu zina.
Magawo a DyScO3 amagwiritsidwa ntchito kwambiri m'ma laboratories a R&D ndi m'malo ogulitsa kuti akule mafilimu oonda pogwiritsa ntchito njira monga pulsed laser deposition (PLD) kapena molecular beam epitaxy (MBE).Mafilimu omwe amachokera amatha kukonzedwanso ndikugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zamagetsi, kukolola mphamvu, zowunikira ndi zipangizo zamakono.
Mwachidule, gawo lapansi la DyScO3 ndi gawo limodzi la kristalo lopangidwa ndi dysprosium, scandium ndi ion oxygen.Amagwiritsidwa ntchito kukulitsa mafilimu owonda kwambiri okhala ndi zinthu zofunika ndikupeza ntchito m'magawo osiyanasiyana monga zamagetsi, mphamvu ndi optics.
