LaAlO3 Substrate
Sharaxaada
LaAlO3Hal crystal waa tan ugu muhiimsan ee warshadaysan, cabirka weyn ee heerkulka sare ee superconducting aflaanta khafiifka ah ee substrate hal walxaha crystal.Koritaankeeda habka Czochralski, 2 inji dhexroor ah iyo hal crystal ka weyn iyo substrate waa la heli karaa Waxay ku habboon tahay soo saarista heerkul sare ee qalabka elektiroonigga ah ee microwave (sida isgaarsiinta fogaanta fog ee heerkulka sare ee miirayaasha microwave superconducting iwm.)

Faa'iidada Joogtada ah ee Dielectric Low
Yaree qallooca isha: Wareegyada elektiroonigga ah iyo nidaamyada isgaarsiinta, joogitaanka dielectric hooseeya waxay caawisaa yaraynta qallooca isha.Alaabta dielectric waxay saameyn kartaa fidinta calaamadaha korantada, taasoo keenaysa luminta calaamadaha iyo dib u dhaca.Qalabka Low-k wuxuu yareeyaa saameyntan, taasoo awood u siinaysa gudbinta calaamadaha saxda ah iyo hagaajinta guud ahaan waxqabadka nidaamka.
Wanaaji hufnaanta dahaarka: Alaabta dielectric waxaa inta badan loo isticmaalaa insulators si ay u go'doomiso qaybaha conductive iyo ka hortagga daadinta.Maaddooyinka joogtada ah ee dielectric hooseeya waxay bixiyaan dahaar wax ku ool ah iyadoo la yareynayo tamarta ka luntay isku xirka korontostatic ee u dhexeeya kirishbooyada ku xiga.Tani waxay keenaysaa korodhka waxtarka tamarta iyo hoos u dhaca isticmaalka tamarta ee nidaamka korontada.
