I-SrTiO3 Substrate
Incazelo
I-crystal eyodwa ye-SrTiO3 inesakhiwo esihle se-lattice se-perovskite structure material.Kuyinto enhle kakhulu ye-substrate yokukhula kwe-epitaxy ye-HTS kanye namafilimu amaningi e-oxide.Isetshenziswe kabanzi ocwaningweni lwamafilimu amancanyana e-superconducting okushisa aphezulu.Ibuye isetshenziswe kabanzi kumafasitela akhethekile optical kanye nekhwalithi ephezulu yokuhlonza i-sputtering.

Incazelo ye-Substrate ye-SrTiO3
I-substrate ye-SrTiO3 isho i-crystalline substrate eyenziwe nge-compound strontium titanate (SrTiO3).I-SrTiO3 iyimpahla ye-perovskite enesakhiwo se-cubic crystal, esibonakala ngokuhlala okuphezulu kwe-dielectric, ukuzinza okuphezulu kokushisa, nokuhambisana okuhle kwe-lattice nezinye izinto eziningi.
Ama-substrates e-SrTiO3 asetshenziswa kabanzi emikhakheni yokufakwa kwefilimu emincane kanye nokukhula kwe-epitaxial.Isakhiwo se-cubic se-SrTiO3 sivumela ukukhula kwamafilimu amancanyana ekhwalithi ephezulu anekhwalithi enhle kakhulu yekristalu kanye nokuminyana okungamaphutha.Lokhu kwenza ama-substrates e-SrTiO3 alungele kakhulu amafilimu e-epitaxial akhulayo kanye ne-heterostructures yezinhlelo zokusebenza ezihlukahlukene.
I-dielectric constant constant ye-SrTiO3 iyenza ifanelekele izinhlelo zokusebenza ezifana nama-capacitor, amadivaysi enkumbulo, namafilimu amancanyana e-ferroelectric.Ukuzinza kwayo okushisayo kuyenza ifanelekele izicelo zokushisa okuphezulu.
Ngaphezu kwalokho, izici ezihlukahlukene ze-SrTiO3, njengokusebenza kwayo kwensimbi emazingeni okushisa aphansi kanye nethuba lokungenisa isimo se-superconducting, ikwenza kube usizo ocwaningweni lwefiziksi yento efingqiwe kanye nokuthuthukiswa kwemishini kagesi kanye ne-optoelectronic.
Kafushane, ama-substrates e-SrTiO3 angama-crystalline substrates enziwe nge-strontium titanate, avame ukusetshenziswa ekufakweni kwefilimu emincane, ukukhula kwe-epitaxial, kanye nohlu olubanzi lwezinhlelo zokusebenza ze-electronic kanye ne-optoelectronic ngenxa yokungaguquguquki okuphezulu kwe-dielectric, ukuzinza kwe-thermal, kanye nezakhiwo ezinhle zokufanisa i-lattice.
