I-LaAlO3 Substrate
Incazelo
LaAlO3Ikristalu eyodwa iyinto ebaluleke kakhulu yezimboni, usayizi omkhulu ophezulu wokushisa ophakeme wefilimu engaphansi kwe-substrate yekristalu eyodwa.Ukukhula ngendlela ye-Czochralski, ama-intshi angu-2 ububanzi kanye nekristalu eyodwa enkulu futhi i-substrate ingatholakala Ilungele ukukhiqizwa kwamadivayisi kagesi we-microwave superconducting ephezulu (njengokuxhumana amabanga amade kuzihlungi ze-microwave ezinezinga eliphezulu lokushisa eliphezulu njll.)

I-Low Dielectric Constant's Advantage
Yehlisa ukuhlanekezela kwesignali: Kumasekhethi e-elekthronikhi nezinhlelo zokuxhumana, ukungaguquki kwe-dielectric ephansi kusiza ukunciphisa ukuhlanekezela kwesignali.Izinto ze-Dielectric zingathinta ukusakazwa kwezimpawu zikagesi, kubangele ukulahlekelwa kwesignali nokubambezeleka.Izinto ze-Low-k zinciphisa le miphumela, zivumela ukudluliswa kwesignali okunembe kakhudlwana futhi kuthuthukise ukusebenza kohlelo lonke.
Thuthukisa ukusebenza kahle kwe-insulation: Izinto ze-dielectric zivame ukusetshenziswa njengama-insulators ukuze kuhlukaniswe izingxenye ze-conductive futhi kuvimbele ukuvuza.Izinto ezingaguquki ze-dielectric eziphansi zinikeza ukwahlukanisa okusebenzayo ngokunciphisa amandla alahleka ekuhlanganisweni kwe-electrostatic phakathi kwamakhondaktha aseduze.Lokhu kubangela ukwanda kokusebenza kahle kwamandla kanye nokunciphisa ukusetshenziswa kwamandla kwesistimu kagesi.
