LaAlO3 Substrate
Kev piav qhia
LaAlO3ib leeg siv lead ua yog qhov tseem ceeb tshaj plaws industrialized, loj-loj kub-kub superconducting nyias zaj duab xis substrate ib qho khoom siv lead ua.Nws txoj kev loj hlob nrog Czochralski txoj kev, 2 ntiv tes hauv txoj kab uas hla thiab loj dua ib qho siv lead ua thiab cov substrate tuaj yeem tau txais Nws yog qhov tsim nyog rau kev tsim cov khoom siv hluav taws xob kub superconducting microwave (xws li kev sib txuas lus ntev hauv high-temperature superconducting microwave filters thiab lwm yam.)

Tsawg Dielectric Constant Qhov Zoo
Txo cov teeb liab distortion: Nyob rau hauv hluav taws xob circuits thiab kev sib txuas lus systems, tsawg dielectric tas li yuav pab txo cov teeb liab distortion.Cov khoom siv dielectric tuaj yeem cuam tshuam rau kev nthuav tawm ntawm cov teeb liab hluav taws xob, ua rau lub teeb liab poob thiab qeeb.Cov ntaub ntawv low-k txo cov teebmeem no, ua kom cov teeb liab kis tau zoo dua thiab txhim kho kev ua haujlwm tag nrho.
Txhim kho rwb thaiv tsev efficiency: cov khoom siv dielectric feem ntau yog siv los ua cov insulators kom cais cov khoom siv hluav taws xob thiab tiv thaiv kom tsis txhob tawg.Cov ntaub ntawv uas tsis tshua muaj dielectric tsis tu ncua muab cov rwb thaiv tsev zoo los ntawm kev txo qis zog poob rau electrostatic coupling ntawm cov neeg nyob ib sab.Qhov no ua rau muaj zog ua kom muaj zog thiab txo qis kev siv hluav taws xob ntawm cov hluav taws xob.
