Kev kho cua sov ntawm nyias zaj duab xis resistor
Lub hom phiaj ntawm kev kho cua sov ntawm cov yeeb yaj kiab kuj yog los tsim ib qho ntawm cov txheej txheem insulating hauv zaj duab xis kom txhim kho qhov kub thiab txias ntawm cov yeeb yaj kiab mus ntev. Kev tsim cov txheej txheem ntawm cov yeeb yaj kiab tsis zoo feem ntau yog qhov kub thiab txias thiab lub sijhawm luv luv, yog li muaj ntau qhov tsis sib xws thiab qee cov txheej txheem metastable tau khaws cia, uas ua rau maj mam ploj ntawm cov teeb meem no thiab maj mam hloov pauv ntawm metastable xeev nyob rau hauv lub sijhawm ua haujlwm ntev. txheej txheem ntawm nyias zaj duab xis, thiab kev ua tau zoo ntawm nyias zaj duab xis maj mam hloov. Los ntawm kev kho cua sov, qee qhov dislocations tsim nyob rau hauv cov txheej txheem deposition tuaj yeem txav mus rau saum npoo thiab ploj mus, thiab cov qoob loo ntawm cov ciam teb poob qis. Yog li ntawd, cov qauv ntawm cov yeeb yaj kiab tau zoo heev, cov yeeb yaj kiab hloov pauv ntawm lub xeev metastable mus rau lub xeev ruaj khov, thiab cov yeeb yaj kiab ua yeeb yaj kiab zoo li ruaj khov. Tsis tas li ntawd, vim hais tias cov zaj duab xis thiab substrate feem ntau yog ob yam khoom sib txawv, nws yog ib qho inevitable uas yuav muaj kev sib nrig sib diffusion thiab tshuaj lom neeg cov tshuaj tiv thaiv ntawm lub interface, uas yuav ua rau maj mam hloov ntawm cov khoom ntawm cov yeeb yaj duab kuj. Ib yam li ntawd, nyob rau saum npoo ntawm zaj duab xis, cov khoom ntawm cov yeeb yaj kiab hloov nrog lub sijhawm vim muaj kev sib txawv thiab cov tshuaj tiv thaiv.
Nws tuaj yeem pom los ntawm cov saum toj no tias qhov kev ua tau zoo ntawm cov yeeb yaj kiab tsis muaj kev kho cua sov tsis ruaj khov txaus, yog li nws yuav tsum xaiv cov txheej txheem kho cua sov uas tsim nyog, xws li kub, sijhawm thiab cua. Feem ntau hais lus, qhov kub thiab txias yuav tsum raug xaiv, vim tias tsuas yog nyob rau ntawm qhov kub siab tuaj yeem ua ntau yam txheej txheem hauv zaj duab xis ua tiav hauv lub sijhawm kho cua sov tsawg. Nyob rau tib lub sijhawm, txheej txheej tiv thaiv ntom ntom yuav tsum tau tsim rau saum npoo ntawm zaj duab xis. Ntxiv nrog rau qhov kev kho cua sov kom zoo thiab lub sijhawm, qhov chaw kho cua sov tsim nyog yuav tsum raug xaiv. Piv txwv li, siv cov cua oxidizing lossis nitriding. Nyob rau hauv txoj kev no, cov txheej txheem rwb thaiv tsev tuaj yeem ua tiav cov qauv zoo heev dispersion, xws li cov khoom tawg yooj yim ntawm molecular linearity, kom qhov kev ruaj ntseg thiab kub ua haujlwm ntawm zaj duab xis tuaj yeem ncav cuag qhov zoo tshaj plaws.
Kev faib tawm ntawm cov khoom siv hluav taws xob
Tam sim no, muaj ntau yam khoom siv los ua cov yeeb yaj kiab, suav nrog cov hlau ntshiab, hlau alloys, hlau sib txuas lossis cermets (kev sib txuas ntawm ceramics thiab hlau), thiab lwm yam, tab sis muaj peb hom khoom siv dav siv hauv monolithic analog integrated circuits thiab zaj duab xis. hybrid circuits: npib tsib xee chromium, chromium silicon thiab chromium silicon oxide cermets, ntawm cov nickel chromium belongs rau cov ntaub ntawv uas tsis muaj zog, thaum chromium silicon thiab chromium silicon oxide yog cov ntaub ntawv muaj zog tiv taus Material Science. Raws li qhov sib txawv ntawm cov ntaub ntawv, feem ntau siv nyias zaj duab xis tiv thaiv cov ntaub ntawv muab faib ua peb hom: nickel chromium, chromium silicon thiab chromium silicon oxide.
