KTaO3 Substrate Definition
I-KTaO3 (i-potassium tantalate) i-substrate ibhekisela kwi-crystalline substrate eyenziwe kwi-compound potassium tantalate (KTaO3).
I-KTaO3 yimpahla ye-perovskite ene-cubic crystal structure efana ne-SrTiO3.I-substrate ye-KTaO3 ineempawu ezenza ukuba ibe luncedo ngakumbi kwiintlobo ezahlukeneyo zophando kunye nezixhobo zokusebenza.I-dielectric ephezulu engaguqukiyo kunye ne-conductivity elungileyo yombane ye-KTaO3 yenza ukuba ilungele izicelo ezifana ne-capacitors, izixhobo zememori, kunye neesekethe ze-elektroniki ze-high-frequency.Ukongeza, ii-substrates ze-KTaO3 zineempawu ezibalaseleyo ze-piezoelectric, zizenza zibe luncedo kwizicelo ze-piezoelectric ezifana nezinzwa, ii-actuator, kunye nezivuni zamandla.
Impembelelo ye-piezoelectric ivumela i-substrate ye-KTaO3 ukuba ivelise iindleko xa iphantsi koxinzelelo lomatshini okanye ukuguqulwa komatshini.Ukongeza, ii-substrates ze-KTaO3 zinokubonisa i-ferroelectricity kumaqondo obushushu aphantsi, zibenza bafaneleke kuphononongo lwe-condensed matter physics kunye nophuhliso lwezixhobo zememori ezingaguqukiyo.
Ngokubanzi, ii-substrates ze-KTaO3 zidlala indima ebalulekileyo kuphuhliso lwezixhobo zombane, i-piezoelectric, kunye ne-ferroelectric.Iipropathi zabo ezifana ne-dielectric constant, conductivity elungileyo yombane, kunye ne-piezoelectricity zibenza zibe yimathiriyeli efanelekileyo yoluhlu olubanzi lwezicelo.
Superconducting Thin Films Inkcazo
Ifilimu encinci ye-superconducting ibhekisela kumgca omncinci wezinto eziphathekayo kunye ne-superconductivity, oko kukuthi, ukukwazi ukuqhuba umbane ngokuxhathisa i-zero.Ezi filimu ziqhele ukwenziwa ngokufaka imathiriyeli ephezulu kwi-substrates kusetyenziswa iindlela ezahlukeneyo zokuyila ezifana nokubekwa komphunga obonakalayo, ukubekwa komphunga wekhemikhali, okanye i-epitaxy yemolekyuli.
