Substrate-ka LSAT
Sharaxaada
(La, Sr) (Al, Ta) O 3 waa kiristaalo aan bislaan ahayn oo bislaaday, kaas oo si fiican ugu habboon heerkul sare oo heerkul sare ah iyo agabyo kala duwan oo oksaydh ah.Waxaa la filayaa in lanthanum aluminate (LaAlO 3) iyo strontium titanate (SrO 3) lagu bedeli doono magnetoelectrics aadka u weyn iyo qalabyada awooda sare leh ee tiro badan oo codsiyo la taaban karo ah.

LaAlO3 Qeexitaan Substrate
Substrate LaAlO3 waxaa loola jeedaa shay gaar ah oo loo isticmaalo substrate ama saldhig u ah codsiyada sayniska iyo tignoolajiyada ee loogu talagalay kobcinta filimada khafiifka ah ee agabka kale duwan.Waxay ka kooban tahay qaab-dhismeedka crystalline ee lanthanum aluminate (LaAlO3), kaas oo inta badan loo isticmaalo goobta dhigaalka filimka khafiifka ah.
Qaybaha LaAlO3 waxay leeyihiin sifooyin ka dhigaya kuwo jecel inay koraan aflaanta khafiifka ah, sida tayada sare ee crystalline, jilicsanaanta wanaagsan ee aan u dhigmin qalabyo kale oo badan, iyo awood u leh inay bixiyaan dusha ku haboon koritaanka epitaxial.
Epitaxial waa habka koritaanka filim khafiif ah oo ku yaala substrate kaas oo atamka filimku ay la socdaan kuwa substrate-ka si ay u sameeyaan qaab-dhismeed si heer sare ah loo amray.
LaAlO3 substrates ayaa si weyn loogu isticmaalaa goobaha sida elektiroonigga ah, optoelectronics, iyo fiisigiska-adag-state, halkaas oo aflaanta dhuuban muhiim u ah codsiyada kala duwan ee qalabka.Sifooyinkeeda gaarka ah iyo la jaanqaadka agabyo badan oo kala duwan ayaa ka dhigaya substrate muhiim u ah cilmi-baarista iyo horumarinta dhinacyadan.
Heerkulka sare ee Superconductors Qeexida
Heerkulka sare ee kondhontarka (HTS) waa maaddooyin muujiya dabeecadda sare ee heerkul aad u sarreeya marka la barbar dhigo kontaroolayaasha caadiga ah.Koontaroolada caadiga ah waxay u baahan yihiin heerkul aad u hooseeya, caadi ahaan ka hooseeya -200°C (-328°F), si loo muujiyo iska caabin koronto eber ah.Taas bedelkeeda, walxaha HTS waxay ku gaari karaan heerkul sare sida -135°C (-211°F) iyo wixii ka sareeya.
