Gawo la LSAT
Kufotokozera
(La, Sr) (Al, Ta) O 3 ndi kristalo wokhwima wosakhala wa crystalline perovskite, womwe umagwirizana bwino ndi ma superconductors otentha kwambiri komanso zinthu zosiyanasiyana za oxide.Zikuyembekezeka kuti lanthanum aluminate (LaAlO 3) ndi strontium titanate (SrO 3) adzakhala m'malo mu magnetoelectrics chimphona ndi superconducting zipangizo mu chiwerengero chachikulu cha ntchito zothandiza.

LaAlO3 Substrate Tanthauzo
Gawo laling'ono la LaAlO3 limatanthawuza chinthu china chomwe chimagwiritsidwa ntchito ngati gawo laling'ono kapena maziko pazasayansi ndiukadaulo pakukulitsa makanema owonda azinthu zina zosiyanasiyana.Amakhala ndi mawonekedwe a crystalline a lanthanum aluminate (LaAlO3), omwe amagwiritsidwa ntchito popanga filimu yopyapyala.
Magawo a LaAlO3 ali ndi zinthu zomwe zimawapangitsa kukhala ofunikira pakukulitsa mafilimu opyapyala, monga mawonekedwe awo apamwamba a crystalline, ma latisi abwino osagwirizana ndi zida zina zambiri, komanso kuthekera kopereka malo oyenera kukula kwa epitaxial.
Epitaxial ndi njira yopangira filimu yopyapyala pagawo laling'ono momwe maatomu a filimuyo amayenderana ndi a gawo lapansi kuti apange dongosolo lolamulidwa kwambiri.
Magawo a LaAlO3 amagwiritsidwa ntchito kwambiri m'magawo monga zamagetsi, ma optoelectronics, ndi fizikiki yolimba, pomwe mafilimu owonda amakhala ofunikira pakugwiritsa ntchito zida zosiyanasiyana.Makhalidwe ake apadera komanso kugwirizana ndi zida zambiri zosiyanasiyana zimapangitsa kuti ikhale gawo lofunikira pakufufuza ndi chitukuko m'magawo awa.
Kutentha kwakukulu kwa Superconductors Tanthauzo
High-temperature superconductors (HTS) ndi zida zomwe zimasonyeza superconductivity pa kutentha kwakukulu poyerekeza ndi superconductors wamba.Ma superconductors wamba amafunikira kutentha kotsika kwambiri, komwe kumakhala pansi -200 ° C (-328 ° F), kuti awonetse kukana kwamagetsi ziro.Mosiyana ndi zimenezi, zipangizo za HTS zimatha kukwaniritsa superconductivity pa kutentha kwambiri -135 ° C (-211 ° F) ndi pamwamba.
