LaAlO3 Substrate Definition
I-substrate ye-LaAlO3 ibhekiselele kwizinto ezithile ezisetyenziswa njengenxalenye engaphantsi okanye isiseko kwizicelo zenzululwazi nezeteknoloji zokukhulisa iifilimu ezibhityileyo zezinye izinto ezahlukeneyo.Iqukethe i-crystalline structure ye-lanthanum aluminate (LaAlO3), esetyenziswa ngokuqhelekileyo kwintsimi yefilimu encinci yokubeka ifilimu.
I-substrates ye-LaAlO3 ineempawu ezenza zibe zinqweneleka ekukhuleni iifilimu ezincinci, ezifana nomgangatho ophezulu we-crystalline, i-lattice efanelekileyo yokungahambi kakuhle kunye nezinye izinto ezininzi, kunye nokukwazi ukubonelela indawo efanelekileyo yokukhula kwe-epitaxial.
I-Epitaxial yinkqubo yokukhulisa ifilimu encinci kwi-substrate apho ii-athomu zefilimu zihambelana nezo ze-substrate ukwenza isakhiwo esilawulwa kakhulu.
I-LaAlO3 substrates zisetyenziswa ngokubanzi kwiinkalo ezifana ne-electronics, optoelectronics, kunye ne-fiziksi yombuso oqinileyo, apho iifilimu ezibhityileyo zibaluleke kakhulu kwiinkqubo ezahlukeneyo zezixhobo.Iimpawu zayo ezizodwa kunye nokuhambelana nezinto ezininzi ezahlukeneyo zenza ukuba i-substrate ebalulekileyo yophando kunye nophuhliso kule mimandla.
High-lobushushu Superconductors Definition
I-high-temperature superconductors (HTS) zizinto ezibonisa i-superconductivity kumaqondo okushisa aphezulu xa kuthelekiswa ne-superconductors eqhelekileyo.Ii-superconductors eziqhelekileyo zifuna amaqondo obushushu aphantsi kakhulu, ngokuqhelekileyo angaphantsi kwe -200 ° C (-328 ° F), ukubonisa ukunganyangeki kombane.Ngokwahlukileyo, izixhobo ze-HTS zinokufikelela kwi-superconductivity kumaqondo obushushu aphezulu -135 ° C (-211 ° F) nangaphezulu.
