I-LSAT Substrate
Incazelo
(La, Sr) (Al, Ta) I-O 3 iyikristalu ye-perovskite engeyona i-crystalline evuthiwe, ehambisana kahle nama-superconductors okushisa aphezulu kanye nezinto ezihlukahlukene ze-oxide.Kulindeleke ukuthi i-lanthanum aluminate (LaAlO 3) kanye ne-strontium titanate (SrO 3) zizoshintshwa kumagnetoelectrics amakhulu kanye namadivayisi e-superconducting ngenani elikhulu lezinhlelo zokusebenza ezingokoqobo.

I-LaAlO3 Substrate Definition
I-LaAlO3 substrate isho into ethile esetshenziswa njenge-substrate noma isisekelo ezinhlelweni zesayensi nezobuchwepheshe zokukhulisa amafilimu amancanyana ezinye izinto ezahlukahlukene.Iqukethe isakhiwo se-crystalline se-lanthanum aluminate (LaAlO3), esivame ukusetshenziswa emkhakheni wokufakwa kwefilimu encane.
Ama-substrates e-LaAlO3 anezakhiwo eziwenza afiseleke ekukhuleni amafilimu amancane, njengekhwalithi yawo ephezulu ye-crystalline, ukungahambisani kahle kwe-lattice nezinye izinto eziningi, kanye nekhono lokuhlinzeka indawo efanelekile yokukhula kwe-epitaxial.
I-Epitaxial inqubo yokukhulisa ifilimu elincanyana ku-substrate lapho ama-athomu efilimu aqondana nalawo e-substrate ukuze akhe isakhiwo esihleleke kakhulu.
Ama-substrates e-LaAlO3 asetshenziswa kakhulu emikhakheni efana ne-electronics, optoelectronics, ne-solid-state physics, lapho amafilimu amancane ebaluleke kakhulu ekusetshenzisweni kwedivayisi ehlukahlukene.Izakhiwo zayo eziyingqayizivele nokuhambisana nezinto eziningi ezahlukene kuyenza ibe i-substrate ebalulekile yocwaningo nokuthuthukiswa kule mikhakha.
I-High-temperature Superconductors Definition
I-High-temperature superconductors (HTS) yizinto ezisetshenziswayo ezibonisa ukusebenza kahle emazingeni okushisa aphakeme uma kuqhathaniswa nama-superconductors avamile.Ama-superconductors avamile adinga amazinga okushisa aphansi kakhulu, ngokuvamile angaphansi kuka-200°C (-328°F), ukuze abonise ukungezwani kukagesi okuyiziro.Ngokuphambene, izinto ze-HTS zingafinyelela i-superconductivity emazingeni okushisa afinyelela ku -135°C (-211°F) nangaphezulu.
