LaAlO3 Substrate Tlhaloso
LaAlO3 substrate e bua ka thepa e ikhethileng e sebelisoang e le setsi kapa setsi sa lits'ebetso tsa mahlale le tsa mahlale bakeng sa ho holisa lifilimi tse tšesaane tsa lisebelisoa tse ling tse fapaneng.E na le sebopeho sa kristale sa lanthanum aluminate (LaAlO3), e atisang ho sebelisoa tšimong ea ho beha filimi e tšesaane.
Li-substrates tsa LaAlO3 li na le thepa e etsang hore li lakatsehe bakeng sa ho hōla lifilimi tse tšesaane, tse kang boleng ba tsona bo phahameng ba kristale, li-lattice tse ntle tse fapaneng le lisebelisoa tse ling tse ngata, le bokhoni ba ho fana ka sebaka se loketseng bakeng sa kholo ea epitaxial.
Epitaxial ke mokhoa oa ho hōlisa filimi e tšesaane holim'a substrate eo liathomo tsa filimi li lumellanang le tsa substrate ho theha mohaho o hlophisitsoeng haholo.
Li-substrates tsa LaAlO3 li sebelisoa haholo libakeng tse kang lisebelisoa tsa elektronike, optoelectronics, le fisiks ea boemo bo tiileng, moo lifilimi tse tšesaane li leng bohlokoa bakeng sa lisebelisoa tse fapaneng tsa lisebelisoa.Thepa ea eona e ikhethang le ho tsamaellana le lisebelisoa tse ngata tse fapaneng li e etsa karolo ea bohlokoa bakeng sa lipatlisiso le nts'etsopele mafapheng ana.
Mocheso o phahameng oa li-Superconductors Tlhaloso
Li-superconductors tse phahameng tsa mocheso (HTS) ke lisebelisoa tse bontšang superconductivity ka mocheso o batlang o le holimo ha o bapisoa le li-superconductors tse tloaelehileng.Li-superconductors tse tloaelehileng li hloka mocheso o tlase haholo, hangata o ka tlase ho -200 ° C (-328 ° F), ho bonts'a ho hana motlakase oa zero.Ka lehlakoreng le leng, lisebelisoa tsa HTS li ka finyella superconductivity ka mocheso o phahameng ho -135 ° C (-211 ° F) le holimo.
