SiGe hmoov, kuj hu uasilicon germanium hmoov, yog ib yam khoom uas tau txais kev saib xyuas zoo hauv kev siv tshuab semiconductor.Kab lus no yog xav piav qhia vim li casSiGeyog dav siv nyob rau hauv ntau yam kev siv thiab tshawb nrhiav nws cov khoom tshwj xeeb thiab qhov zoo.
Silicon germanium hmoovyog cov khoom sib xyaw ua ke ntawm silicon thiab germanium atoms.Kev sib xyaw ua ke ntawm ob lub ntsiab lus tsim cov khoom siv nrog cov khoom zoo kawg nkaus uas tsis pom muaj nyob hauv silicon ntshiab lossis germanium.Ib qho ntawm cov laj thawj tseem ceeb rau kev sivSiGeyog nws zoo heev compatibility nrog silicon-based technologies.
Kev koom ua keSiGerau hauv cov khoom siv silicon muaj ntau qhov zoo.Ib qho ntawm qhov zoo tshaj plaws yog nws lub peev xwm los hloov cov khoom hluav taws xob ntawm silicon, yog li txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob.Piv rau silicon,SiGemuaj ntau dua electron thiab qhov txav mus los, tso cai rau kev thauj mus los sai dua electron thiab nce cov cuab yeej ceev.Cov cuab yeej no tshwj xeeb yog muaj txiaj ntsig zoo rau cov ntawv thov siv ntau zaus, xws li kev sib txuas lus wireless thiab kev sib koom ua ke ntawm kev kub ceev.
Ntxiv thiab,SiGemuaj qhov sib txawv qis dua li silicon, uas tso cai rau nws nqus thiab tawm lub teeb kom zoo dua.Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo rau cov khoom siv optoelectronic xws li photodetectors thiab lub teeb-emitting diodes (LEDs).SiGekuj muaj cov thermal conductivity zoo heev, tso cai rau nws kom tshem tawm cov cua sov kom zoo, ua rau nws zoo tagnrho rau cov khoom siv uas xav tau kev tswj xyuas thermal zoo.
Lwm qhov laj thawj rauSiGeKev siv dav dav yog nws txoj kev sib raug zoo nrog cov txheej txheem tsim khoom silicon uas twb muaj lawm.SiGe hmoovtuaj yeem yooj yim tov nrog silicon thiab tom qab ntawd tso rau hauv silicon substrate siv cov txheej txheem semiconductor tsim xws li tshuaj vapor deposition (CVD) lossis molecular beam epitaxy (MBE).Qhov kev sib txuam seamless no ua rau nws muaj txiaj ntsig zoo thiab ua kom muaj kev hloov pauv zoo rau cov tuam txhab uas twb tau tsim cov chaw tsim khoom siv silicon.
SiGe hmoovtseem tuaj yeem tsim strained silicon.Lim yog tsim nyob rau hauv silicon txheej los ntawm depositing ib tug nyias txheej ntawmSiGenyob rau sab saum toj ntawm silicon substrate thiab ces xaiv tshem tawm cov germanium atoms.Cov kab mob no hloov cov silicon cov qauv band, ntxiv dag zog rau nws cov khoom hluav taws xob.Strained silicon tau dhau los ua ib qho tseem ceeb hauv cov khoom siv hluav taws xob ua haujlwm siab, ua kom muaj kev hloov pauv sai dua thiab siv hluav taws xob qis dua.
Ntxiv rau,SiGe hmoovmuaj ntau yam kev siv hauv kev lag luam ntawm cov khoom siv thermoelectric.Cov khoom siv thermoelectric hloov cov cua sov mus rau hauv hluav taws xob thiab rov ua dua, ua rau lawv tseem ceeb hauv kev siv xws li kev tsim hluav taws xob thiab cov tshuab ua kom txias.SiGemuaj cov thermal conductivity thiab tunable hluav taws xob, muab cov khoom siv zoo tshaj plaws rau kev txhim kho cov khoom siv hluav taws xob zoo.
Hauv kev xaus,SiGe hmoov or silicon germanium hmoovmuaj ntau yam zoo thiab kev siv hauv kev siv tshuab semiconductor.Nws compatibility nrog cov txheej txheem silicon uas twb muaj lawm, cov khoom hluav taws xob zoo heev thiab thermal conductivity ua rau nws cov khoom nrov.Txawm hais tias kev txhim kho kev ua tau zoo ntawm kev sib xyaw ua ke, tsim cov khoom siv optoelectronic, lossis tsim cov khoom siv hluav taws xob zoo,SiGetxuas ntxiv mus ua pov thawj nws tus nqi raws li ib tug multifunctional khoom.Raws li kev tshawb fawb thiab thev naus laus zis txuas ntxiv mus, peb cia siab tiasSiGe hmoovlos ua lub luag haujlwm tseem ceeb tshaj plaws hauv kev tsim lub neej yav tom ntej ntawm cov khoom siv semiconductor.
