I-KTaO3 Substrate
Incazelo
I-Potassium tantalate single crystal iwuhlobo olusha lwekristalu ene-perovskite ne-pyrochlore structure.Inamathemba emakethe abanzi ekusetshenzisweni kwamafilimu amancane ama-superconducting.Ingahlinzeka ngama-crystal substrates amasayizi ahlukahlukene kanye nokucaciswa ngekhwalithi ephelele.

Incazelo ye-KTaO3 Substrate
I-KTaO3 (potassium tantalate) substrate ibhekisela ku-crystalline substrate eyenziwe nge-compound potassium tantalate (KTaO3).
I-KTaO3 iyimpahla ye-perovskite enesakhiwo se-cubic crystal esifana ne-SrTiO3.I-substrate ye-KTaO3 inezinto ezenza isebenziseke ngokukhethekile ocwaningweni oluhlukahlukene nasezinhlelweni zokusebenza zedivayisi.I-dielectric ephezulu engaguquki kanye ne-conductivity kagesi enhle ye-KTaO3 iyenza ifanelekele izinhlelo zokusebenza ezifana nama-capacitor, amadivaysi enkumbulo, namasekhethi e-electronic-frequency aphezulu.Ngaphezu kwalokho, ama-substrates e-KTaO3 anezinto ezinhle kakhulu ze-piezoelectric, eziwenza abe usizo ezinhlelweni ze-piezoelectric njengezinzwa, ama-actuator, nezivuni zamandla.
Umphumela we-piezoelectric uvumela i-substrate ye-KTaO3 ukuthi ikhiqize amashaji lapho ingaphansi kokucindezeleka komshini noma ukuwohloka komshini.Ngaphezu kwalokho, ama-substrates e-KTaO3 angabonisa i-ferroelectricity emazingeni okushisa aphansi, awenze afaneleke ocwaningweni lwe-condensed matter physics kanye nokuthuthukiswa kwemishini yenkumbulo engaguquki.
Sekukonke, ama-substrates e-KTaO3 adlala indima ebalulekile ekuthuthukisweni kwemishini kagesi, i-piezoelectric, ne-ferroelectric.Izakhiwo zabo ezifana ne-high dielectric constant, conductivity kagesi enhle, kanye ne-piezoelectricity zizenza zibe yizinto ezisetshenziswayo ezingaphansi kwezinhlelo eziningi zokusebenza.
I-Superconducting Thin Films Definition
Ifilimu encane ene-superconducting ibhekisela kungqimba oluncane lwempahla ene-superconductivity, okungukuthi, ikhono lokuqhuba amandla kagesi ngokumelana ne-zero.Lawa mafilimu ngokuvamile enziwa ngokufaka izinto ze-superconducting kuma-substrates kusetshenziswa amasu okwakha ahlukahlukene afana nokufakwa komhwamuko obonakalayo, ukufakwa komhwamuko wamakhemikhali, noma i-epitaxy ye-molecular beam.
