LSAT Substrate
Tsanangudzo
(La, Sr) (Al, Ta) O 3 ikristaro yakakura isiri-crystalline perovskite, iyo yakanyatsoenderana nepamusoro tembiricha superconductors uye akasiyana oxide zvinhu.Zvinotarisirwa kuti lanthanum aluminate (LaAlO 3) uye strontium titanate (SrO 3) achatsiviwa muhofori magnetoelectrics uye superconducting midziyo munhamba huru dzinoshanda mafomu.

LaAlO3 Substrate Tsanangudzo
LaAlO3 substrate inoreva chimwe chinhu chinoshandiswa se substrate kana hwaro mune zvesainzi uye tekinoroji mashandisirwo ekukura mafirimu matete ezvimwe zvinhu zvakasiyana.Iyo ine crystalline chimiro che lanthanum aluminate (LaAlO3), iyo inowanzoshandiswa mumunda wekuonda kwemafirimu deposition.
LaAlO3 substrates ine zvivakwa zvinoita kuti zvidikanwe pakukura mafirimu matete, akadai seyepamusoro crystalline mhando, yakanaka lattice kusapindirana nezvimwe zvinhu zvakawanda, uye kugona kupa nzvimbo yakakodzera yekukura epitaxial.
Epitaxial inzira yekukura firimu rakatetepa pane substrate umo maatomu emufirimu anowirirana neayo eiyo substrate kuita chimiro chakanyatso kurongeka.
LaAlO3 substrates inoshandiswa zvakanyanya muminda yakadai semagetsi, optoelectronics, uye solid-state fizikisi, uko mafirimu matete akakosha kune akasiyana mashandisirwo emidziyo.Hunhu hwayo hwakasiyana uye kuenderana nezvinhu zvakawanda zvakasiyana zvinoita kuti ive yakakosha substrate yekutsvagisa nekusimudzira muminda iyi.
High-temperature Superconductors Tsanangudzo
High-temperature superconductors (HTS) zvinhu zvinoratidza superconductivity pane tembiricha yakakwira zvichienzaniswa neyakajairika superconductors.Masuperconductors akajairika anoda tembiricha yakaderera zvakanyanya, kazhinji pazasi -200 ° C (-328 ° F), kuratidza zero kupikisa magetsi.Mukupesana, HTS zvinhu zvinogona kuwana superconductivity patembiricha yakakwira se -135 ° C (-211 ° F) uye pamusoro.
