DyScO3 Substrate Definition
I-DyScO3 (dysprosium scandate) substrate ibhekisela ohlotsheni oluthile lwe-substrate material evame ukusetshenziswa emkhakheni wokukhula kwefilimu emincane kanye ne-epitaxy.Kuyi-crystal substrate eyodwa enesakhiwo esithile sekristalu esakhiwe i-dysprosium, i-scandium nama-ion ion umoya-mpilo.
Ama-substrates e-DyScO3 anezinto ezimbalwa ezifiselekayo eziwenza afanelekele izinhlelo zokusebenza ezihlukahlukene.Lokhu kufaka phakathi amaphuzu ancibilikayo aphezulu, ukuzinza okuhle kwe-thermal, nokungafani kwe-lattice nezinto eziningi ze-oxide, okuvumela ukukhula kwamafilimu amancane e-epitaxial wekhwalithi ephezulu.
Lawa ma-substrates afaneleka kakhulu ukukhulisa amafilimu amancane e-oxide ayinkimbinkimbi anezindawo ezifiselekayo, njenge-ferroelectric, ferromagnetic noma izinto zokushisa eziphezulu ze-superconducting.Ukungafani kwe-lattice phakathi kwe-substrate nefilimu kubangela uhlobo lwefilimu, olulawula futhi luthuthukise izici ezithile.
Ama-substrates e-DyScO3 avame ukusetshenziswa kulabhorethri ye-R&D nasezindaweni zezimboni ukukhulisa amafilimu amancanyana ngamasu afana ne-pulsed laser deposition (PLD) noma i-molecular beam epitaxy (MBE).Amafilimu atholakalayo angaphinde acutshungulwe futhi asetshenziswe ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa i-electronics, ukuvunwa kwamandla, izinzwa kanye nemishini yezithombe.
Ngamafuphi, i-substrate ye-DyScO3 iyi-substrate ye-crystal eyodwa eyakhiwe i-dysprosium, i-scandium ne-oxygen ions.Asetshenziselwa ukukhulisa amafilimu amancane anekhwalithi ephezulu anezindawo ezifiselekayo futhi athole izinhlelo zokusebenza emikhakheni ehlukahlukene efana ne-electronics, amandla kanye ne-optics.
