KTaO3 Substrate Tlhaloso
KTaO3 (potassium tantalate) substrate e bua ka karoloana ea kristale e entsoeng ka motsoako oa potassium tantalate (KTaO3).
KTaO3 ke thepa ea perovskite e nang le sebopeho sa kristale sa cubic se tšoanang le SrTiO3.Karolo e ka tlase ea KTaO3 e na le thepa e e etsang hore e be molemo ka ho khetheha mefuteng e fapaneng ea lipatlisiso le lits'ebetsong tsa lisebelisoa.Dielectric tse phahameng tsa kamehla le tse ntle tsa motlakase tsa KTaO3 li etsa hore e tšoanelehe bakeng sa lits'ebetso tse joalo ka li-capacitor, lisebelisoa tsa memori, le li-circuits tsa elektroniki tse phahameng haholo.Ntle le moo, li-substrates tsa KTaO3 li na le thepa e ntle haholo ea piezoelectric, e li etsang hore li be molemo bakeng sa lits'ebetso tsa piezoelectric joalo ka lisensara, li-actuator, le likotulo tsa matla.
Phello ea piezoelectric e lumella substrate ea KTaO3 ho hlahisa litefiso ha e le tlas'a khatello ea mochine kapa ho senyeha ha mechine.Ntle le moo, li-substrates tsa KTaO3 li ka bonts'a ferroelectricity ka mocheso o tlase, tsa etsa hore e be tsa bohlokoa bakeng sa thuto ea condensed matter physics le nts'etsopele ea lisebelisoa tsa memori tse sa fetoheng.
Ka kakaretso, li-substrates tsa KTaO3 li bapala karolo ea bohlokoa ntlafatsong ea lisebelisoa tsa elektroniki, piezoelectric le ferroelectric.Thepa ea bona e kang high dielectric constant, conductivity e ntle ea motlakase, le piezoelectricity li etsa hore e be lisebelisoa tse loketseng tsa substrate bakeng sa lits'ebetso tse fapaneng.
Superconducting Thin Films Tlhaloso
Filimi e tšesaane e nang le superconducting e bua ka lesela le lesesaane la thepa e nang le superconductivity, ke hore, bokhoni ba ho tsamaisa motlakase ka ho hanyetsa zero.Lifilimi tsena hangata li etsoa ka ho kenya lisebelisoa tsa superconducting holim'a li-substrates ho sebelisoa mekhoa e fapaneng ea ho etsa joalo ka mouoane oa 'mele, deposition ea mouoane oa lik'hemik'hale, kapa epitaxy ea molek'hule.
