DyScO3 Substrate Definition
I-DyScO3 (i-dysprosium scandate) i-substrate ibhekisela kuhlobo oluthile lwe-substrate yezinto eziqhelekileyo ezisetyenziswa kwintsimi yokukhula kwefilimu encinci kunye ne-epitaxy.I-crystal substrate enye kunye nesakhiwo esithile se-crystal esakhiwe nge-dysprosium, i-scandium kunye ne-oxygen ions.
I-DyScO3 substrates zineempawu ezininzi ezinqwenelekayo ezenza ukuba zilungele usetyenziso oluhlukeneyo.Ezi ziquka iindawo eziphezulu zokunyibilika, ukuzinza okuhle kwe-thermal, kunye ne-lattice engafanelekanga kunye nezixhobo ezininzi ze-oxide, ezenza ukukhula kweefilimu ezinqabileyo ze-epitaxial ezikumgangatho ophezulu.
Ezi substrates zilungele ukukhulisa iifilimu ezibhityileyo zeoxide ezintsonkothileyo ezineempawu ezinqwenelekayo, ezinje nge-ferroelectric, i-ferromagnetic okanye i-high-temperature superconducting materials.Ukungahambelani kwelathisi phakathi kwesubstrate kunye nefilim idala ubunzima befilimu, elawula kwaye iphucule iimpawu ezithile.
Ii-substrates ze-DyScO3 ziqhele ukusetyenziswa kwiilebhu ze-R&D nakwiindawo zoshishino ukukhulisa iifilimu ezibhityileyo ngobuchule obufana ne-pulsed laser deposition (PLD) okanye i-molecular beam epitaxy (MBE).Iifilimu ezibangelwayo zinokuthi ziqhubekiswe ngakumbi kwaye zisetyenziswe kuluhlu lwezicelo, kubandakanywa i-electronics, ukuvunwa kwamandla, izinzwa kunye nezixhobo zefotonic.
Isishwankathelo, i-substrate ye-DyScO3 yi-crystal substrate enye eyenziwe nge-dysprosium, i-scandium kunye ne-oxygen ion.Zisetyenziselwa ukukhulisa iifilimu ezikumgangatho ophezulu ezibhityileyo ezineempawu ezinqwenelekayo kwaye zifumane izicelo kwiinkalo ezahlukeneyo ezifana ne-elektroniki, amandla kunye ne-optics.
