SrTiO3 Substrate Inkcazo
I-substrate ye-SrTiO3 ibhekisa kwi-crystalline substrate eyenziwe nge-compound strontium titanate (SrTiO3).I-SrTiO3 yimpahla ye-perovskite ene-cubic crystal structure, ebonakaliswa yi-dielectric rhoqo, ukuzinza okuphezulu kwe-thermal, kunye ne-lattice efanelekileyo ehambelana nezinye izinto ezininzi.
Ii-substrates ze-SrTiO3 zisetyenziswa ngokubanzi kwiindawo zokubeka ifilimu encinci kunye nokukhula kwe-epitaxial.Ulwakhiwo lwe-cubic lwe-SrTiO3 luvumela ukukhula kweefilimu ezikumgangatho ophezulu ezibhityileyo ezinomgangatho ogqwesileyo wekristale kunye noxinzelelo oluphantsi lwesiphene.Oku kwenza ii-substrates ze-SrTiO3 zilungele kakhulu ukukhula kweefilimu ze-epitaxial kunye ne-heterostructures kwizicelo ezahlukeneyo.
I-dielectric constant constant ye-SrTiO3 iyenza ilungele izicelo ezifana ne-capacitors, izixhobo zememori, kunye neefilim ezincinci ze-ferroelectric.Ukuzinza kwayo kwe-thermal kwenza ukuba ifaneleke kwizicelo eziphezulu zokushisa.
Ngaphaya koko, iipropathi ezahlukahlukeneyo ze-SrTiO3, ezifana ne-metallic conductivity kumaqondo obushushu aphantsi kunye nokuba nokwenzeka kokunyanzeliswa kwe-superconducting state, zenza ukuba ibe luncedo kuphando lwefiziksi yomba ocuthiweyo kunye nophuhliso lwezixhobo zombane kunye ne-optoelectronic.
Isishwankathelo, ii-substrates ze-SrTiO3 ziyi-crystalline substrates ezenziwe nge-strontium titanate, ezisetyenziswa ngokuqhelekileyo kwi-deposition yefilimu encinci, ukukhula kwe-epitaxial, kunye noluhlu olubanzi lwezicelo ze-elektroniki kunye ne-optoelectronic ngenxa ye-dielectric rhoqo, ukuzinza kwe-thermal, kunye neempawu ezintle zokuhambelana ne-lattice.
