Lub hauv paus rau phau ntawv
Fais fab thev naus laus zis yog lub hauv paus ntawm cov khoom siv hluav taws xob niaj hnub, thiab thev naus laus zis kev nce qib, qhov kev thov tau rau kev txhim kho lub zog muaj zog txuas ntxiv nce. Nyob rau hauv cov ntsiab lus no, kev xaiv ntawm semiconductor cov khoom siv ua qhov tseem ceeb heev. Thaum cov khoom silicon (si) semiconductors tseem dav siv, cov khoom siv xwm txheej tshiab zoo li gallium carbide (gan) thiab silicon carredly tau txais koob meej hauv kev ua haujlwm siab thev naus laus zis. Kab lus no yuav tshawb txog qhov sib txawv ntawm peb cov ntaub ntawv hauv lub zog siv hluav taws xob, thiab cov kev lag luam tam sim no kom nkag siab yog vim li cas Gan thiab Sic tau ua qhov tseem ceeb hauv cov tshuab hluav taws xob yav tom ntej.
1. Silicon (Si) - lub zog qub semiconductor cov khoom
1.1 tus yam ntxwv thiab zoo
Silicon yog cov khoom siv pioner nyob rau hauv lub zog semiconductor teb, nrog kaum xyoo ntawm kev thov hauv kev lag luam hluav taws xob. Cov cuab yeej ua si si formature freatures feature Cov txheej txheem tsim khoom thiab cov txiaj ntsig dav, muab cov txiaj ntsig dav zoo li tus nqi qis thiab tsim tau cov khoom siv sib txuas zoo. Silicon cov cuab yeej ua kom zoo sib xws, ua rau lawv haum rau ntau cov khoom siv hluav taws xob hauv hluav taws xob, los ntawm cov khoom siv hluav taws xob hluav taws xob muaj zog rau cov tshuab hluav taws xob siab.
1.2 kev txwv
Txawm li cas los xij, raws li qhov kev thov rau kev ua haujlwm siab dua thiab kev ua tau zoo hauv cov khoom siv fais fab loj tuaj, cov kev txwv ntawm cov twj ua kom pom tseeb. Ua ntej, silicon ua tsis tau zoo nyob rau hauv cov zaus nyob rau ntau zaus thiab kev mob siab, ua rau muaj zog nce hluav taws xob thiab txo kev ua haujlwm. Ib qho ntxiv, silicon lub qis qis thermal conductivity ua thermal kev tswj hwm sib luag hauv cov ntawv thov siab, cuam tshuam rau kev ntseeg tau thiab lub neej.
1.3 chaw thov

2. Gallium nitride (Gan) - ib qho kev ua haujlwm loj
2.1 cov yam ntxwv thiab cov txiaj ntsig zoo
Gallium nitride yog bandgap davSemiconductorCov khoom siv uas muaj cim los ntawm lub siab sib tawg teb, muaj zog hluav taws xob musility, thiab qis on-resistance. Piv rau silicon, gan li lag luam tuaj yeem ua haujlwm ntawm cov nquag ua haujlwm ntau dua, txo qis qhov loj ntawm cov khoom siv fais fab thiab nce lub hwj chim ntom ntom. Ntxiv mus, Gan cov khoom siv tuaj yeem txhim kho lub zog ua haujlwm tau zoo vim lawv cov kev ua kom poob qis, tshwj xeeb tshaj yog hauv nruab nrab rau cov ntawv thov tsawg, kev siv cov ntawv thov siab.
2.2 Kev Txwv
Txawm hais tias muaj qhov ua tau zoo ntawm Gan, nws cov nqi tsim khoom nyob hauv siab, txwv nws siv rau cov kev siv high-ends thiab loj yog qhov tseem ceeb. Ib qho ntxiv, GAN thev naus laus zis tseem nyob rau theem pib ntawm kev txhim kho, nrog kev ntseeg tau ntev thiab loj ntau lawm kev loj hlob yuav tsum tau lees paub ntxiv.
2.3 thaj chaw thov
Gan pab kiag li lawm thiab cov yam ntxwv zoo ua haujlwm tau coj mus rau lawv cov khoom siv sai sai, 5G txuas lus sib txuas lus, thiab cov tshuab hluav taws xob sib txuas lus, thiab aerospace electronics. Raws li thev naus laus zis thiab cov nqi txo qis, gan yuav tsum ua lub luag haujlwm ntau dua nyob rau hauv cov kev siv dav dav.
3. Silicon Carbide (Sic) - Cov Khoom Uas Nyiam Tshaj Rau Cov Kev Siv Voltage High
3.1 Cov Cwj Pwm thiab Qhov Zoo
Silicon carbide yog lwm bandgap dav semiconductor cov khoom siv nrog ib tug loj dua kev sib cav sib haum, thiab hluav taws xob kev ua haujlwm tshaj li silicon. Sic lingle nyob rau hauv high-voltage thiab high-fais kev siv, tshwj xeeb hauv cov tsheb hluav taws xob (EVS) thiab muaj inverters. Sic lub siab voltage zam thiab qis dua hloov cov poob ua nws txoj kev xaiv zoo tshaj plaws rau kev hloov kho lub zog zoo thiab hluav taws xob ua kom zoo dua qub.
3.2 kev txwv
Zoo ib yam li GAN, SIC cov khoom siv yog kim rau chaw tsim khoom, nrog cov txheej txheem ntau lawm. Qhov kev txwv no txwv lawv siv rau cov ntawv thov siab zoo xws li EV lub zog hluav taws xob, txuas ntxiv txuas ntxiv mus ntxiv rau cov khoom siv hluav taws xob, thiab cov khoom siv ntse ntse.
3.3 thaj chaw thov
Sic lub zog, qib siab-vuam ua rau nws tau dav nyob rau hauv lub zog hluav taws xob thiab cov khoom siv hluav taws xob muaj zog, cua lub tshuab hluav taws xob, thiab ntau dua. Raws li kev ua lag luam thov loj hlob thiab thev naus laus zis kev nce qib, daim ntawv thov ntawm cov khoom siv SIC hauv cov teb no yuav txuas ntxiv.
4. Kev Ntsuam Xyuas Kev Lag Luam
4.1 kev loj hlob sai ntawm Gan thiab Sic lag luam
Tam sim no, lub zog ua haujlwm thev naus laus zis tab tom hloov pauv, maj mam hloov los ntawm cov khoom silicon rau gan thiab silicat. Raws li kev tshawb fawb kev tshawb fawb, kev ua lag luam rau Gan thiab SIC cov khoom siv tau nrawm nrawm dua thiab yuav tsum tau txuas ntxiv nws txoj kev loj hlob ntawm cov kev loj hlob hauv lub xyoo tom ntej. Cov txheej txheem no feem ntau yog tsav los ntawm ntau yam:
- ** Kev nce ntawm hluav taws xob cov tsheb **: raws li kev ua lag luam thaum EV tau sai, qhov kev thov rau high-efficiency, high-voltage zog shardonductors nce ntxiv. Sic pab kiag li lawm, vim lawv cov kev ua tau zoo tshaj plaws hauv cov ntawv thov siab-voltage, tau dhau los ua qhov kev xaiv uas nyiam tshaj plaws rauEP lub zog hluav taws xob.
- ** Kev tsim kho dua tshiab ntxiv ** Sic pab kiag li lawm, nrog lawv cov kev ua tau zoo thiab kev ntseeg tau, tau siv dav hauv cov kab ke no.
- ** Sedit cov neeg siv khoom siv khoom lag luam ** Raws li cov neeg siv khoom hluav taws xob zoo li tau txais kev ua tau zoo thiab lub zog roj teeb tau vim lawv cov yam ntxwv ntau dua thiab muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo.
4.2 Vim li cas xaiv Gan thiab Sic
Qhov dav dav rau GAN thiab SIC stems feem ntau los ntawm lawv cov kev ua tau zoo tshaj li silicon li.
- ** Dua rau qhov siab dua ** Qhov no yog qhov tshwj xeeb tshaj yog hauv cov tsheb hluav taws xob, txuas ntxiv dua tshiab, thiab ua haujlwm siab cov neeg siv khoom siv hluav taws xob.
- ** Me me loj me me **: Vim tias Gan thiab Sic cov khoom siv tuaj yeem txo cov neeg tsim khoom ntau dua, muaj cov zog hluav taws xob tuaj yeem txo qhov loj tag nrho cov hluav taws xob loj. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev siv tshuaj miniaturization thiab lub teeb ci tsim, xws li cov cuab yeej siv hluav taws xob thiab cov cuab yeej siv aerospace.
- ** Ntxiv kev ntseeg tau ": SIC cov cuab yeej pom tshwj xeeb kev ruaj ntseg thiab kev ntseeg tau nyob hauv ib puag ncig, txo qhov xav tau rau cov cua txias sab nraud thiab txuas ntxiv ntaus ntawv siv sia.
5. Xaus
Nyob rau hauv cov evolution ntawm lub zog hluav taws xob niaj hnub no, kev xaiv ntawm semiconductor cov khoom siv ncaj qha cuam tshuam cov txheej txheem kev ua haujlwm thiab cov peev xwm thov. Thaum silicon tseem muaj yeej cov kev siv hluav taws xob ib txwm ua lag luam, Gan thiab Sic Technologies tau sai sai ua cov kev xaiv zoo, thiab cov tshuab hluav taws xob siab raws li lawv paub tab.
Gan tau txais cov neeg siv khoomKhoom siv hluav taws xobthiab kev sib txuas lus vim nws cov yam ntxwv zoo thiab muaj txiaj ntsig zoo, yog ua ib qho khoom siv tseem ceeb, muaj cov khoom tseem ceeb hauv hluav taws xob tsheb thiab lub zog txuas ntxiv. Raws li cov nqi txo thiab thev naus laus zis, Gan thiab Sic yuav tsum tau hloov cov ntaub ntawv silicon hauv cov khoom siv uas dav dav, kev tsav tsheb fais fab cuab yeej rau theem tshiab ntawm kev loj hlob.
Qhov kev tawm tsam no tau coj los ntawm Gan thiab Sic yuav tsis tsuas yog hloov cov kev lag luam hluav taws xob, thawb lawv mus rau qhov siab dua thiab ntau lub neej ib puag ncig cov lus qhia.
