sic txheej Silicon carbide txheej SiC txheej coated ntawm Graphite substrate rau Semiconductor

SiC muaj cov khoom siv lub cev thiab tshuaj lom neeg zoo heev, xws li qhov kub siab, qhov nyuaj siab, tiv taus corrosion thiab oxidation tsis kam. Tshwj xeeb tshaj yog nyob rau hauv qhov ntau ntawm 1800-2000 ℃, SiC muaj kev tiv thaiv ablation zoo. Yog li ntawd, nws muaj kev cia siab dav dav hauv kev siv dav hlau, khoom siv riam phom thiab lwm yam teb. Txawm li cas los xij, SiC nws tus kheej tsis tuaj yeem siv uaib qho kev tsim khocov khoom siv,yog li ntawd, txoj kev txheej txheem feem ntau yog siv los ua kom siv nws txoj kev hnav tsis kam thiab ablation resistance.

Silicon carbide(SIC) cov khoom siv semiconductor yog tiam thib peb seCov khoom siv miconductor tsim los ntawm thawj tiam khoom semiconductor (Si, GE) thiab tiam thib ob compound semiconductor khoom (GaAs, gap, InP, thiab lwm yam). Raws li cov khoom siv semiconductor dav dav, silicon carbide muaj cov yam ntxwv ntawm qhov dav dav dav dav, lub zog tawg siab, kev ua kom sov siab, kev thauj khoom sai, dielectric tsis tu ncua me me, tiv taus hluav taws xob muaj zog thiab kev ruaj khov tshuaj zoo. Nws tuaj yeem siv los tsim ntau yam khoom siv zaus siab thiab muaj zog nrog kev tiv taus kub siab thiab tuaj yeem siv rau lub sijhawm uas cov khoom siv silicon tsis muaj peev xwm, lossis tsim cov nyhuv uas cov khoom siv silicon nyuaj rau tsim hauv kev siv dav dav.

Daim ntawv thov tseem ceeb: siv rau kev txiav hlau ntawm 3-12 nti monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, thiab lwm yam. Cov ntaub ntawv ua khoom siv rau kev lag luam photovoltaic hnub ci, kev lag luam semiconductor thiab kev lag luam siv lead ua piezoelectric.Siv rau hauvsemiconductor, xob laim pas nrig, lub voj voog hluav taws xob, daim ntawv thov kub siab, lub tshuab ntes ultraviolet, cov khoom siv qauv, astronomy, disc nres, clutch, diesel particulate lim, filament pyrometer, ceramic zaj duab xis, txiav cuab yeej, cua sov, nuclear roj, hniav nyiaj hniav kub, hlau, cov khoom siv tiv thaiv, catalyst txhawb nqa thiab lwm yam teb
