Silicon carbide ua haujlwm li cas?

Tib neeg nyob rau hauv 1905 pom nyob rau hauv lub meteoritesilicon carbide, tam sim no mas los ntawm hluavtaws, Jiangsu silicon carbide muaj ntau yam kev siv, kev lag luam span yog loj, yuav siv tau rau monocrystalline silicon, polysilicon, potassium arsenide, quartz muaju, hnub ci photovoltaic kev lag luam, semiconductor kev lag luam, piezoelectric siv lead ua kev lag luam engineering cov ntaub ntawv.

Lub cim thib peb ntawm cov khoom siv semiconductor nrog nws cov yam ntxwv zoo heev, cov ntawv thov yav tom ntej yog qhov dav heev. Kev tshawb fawb thiab kev loj hlob ntawmsilicon carbidechips nyob rau hauv Tuam Tshoj yog tseem nyob rau hauv thawj theem, daim ntawv thov ntawm silicon carbide chips nyob rau hauv lub hiav txwv yog tsawg, txoj kev loj hlob ntawmsilicon carbidecov ntaub ntawv kev lag luam tsis muaj kev txhawb nqa ntawm downstream daim ntawv thov kev lag luam. Thaum siv los ua cov khoom siv dag zog, nws feem ntau siv nrog cov pa roj carbon fiber ntau lossis iav fiber ntau, feem ntau cov hlau muaj zog (xws li txhuas) thiab ceramics, xws li cov ntaub thaiv npog rau lub dav hlau dav hlau, cov hniav cav, cov thawv tsaws iav thiab cov khoom siv fuselage, thiab lwm yam. kuj tuaj yeem siv los ua cov khoom ua kis las, thiab nws cov fiber ntau luv luv tuaj yeem siv los ua cov khoom siv rauv kub kub.

Qhov ntxhibsilicon carbidecov khoom tau muab nkag rau hauv qhov ntau, tab sis kev siv nano-scalesilicon carbidehmoov nrog cov ntsiab lus siab heev tsis tuaj yeem tsim kev lag luam ntawm nplai hauv lub sijhawm luv luv. Silicon carbide cov ntaub ntawv tuaj yeem muaj kev cuam tshuam hauv kev siv photovoltaic inverters. Lub cim thib peb ntawm cov khoom siv semiconductor yog dav band gap semiconductor cov ntaub ntawv, tseem hu ua cov ntaub ntawv kub kub semiconductor, feem ntau suav nrog silicon carbide, gallium nitride, aluminium nitride, zinc oxide, pob zeb diamond thiab lwm yam.

Nyob rau hauv daim ntawv thov ntawm photovoltaic

Photovoltaic inverter yog qhov tseem ceeb heev rau kev tsim hluav taws xob photovoltaic, tsis yog tsuas yog muaj qhov ncaj qha AC hloov dua siab tshiab, tab sis kuj muaj cov haujlwm ntawm lub hnub ci cell muaj nuj nqi thiab kev tiv thaiv kev tiv thaiv kev ua haujlwm mus rau qhov loj. Nws muaj kev ua haujlwm tsis siv neeg thiab kev kaw haujlwm, kev tswj xyuas lub zog siab, kev ua haujlwm sib cais ua haujlwm (rau kab sib txuas sib txuas), tsis siv neeg hloov hluav taws xob hloov ua haujlwm (rau kab sib txuas sib txuas), DC nrhiav pom muaj nuj nqi (rau kab sib txuas sib txuas) , DC grounding detection muaj nuj nqi (rau kab sib txuas nrog), thiab lwm yam.

Cov ntawv thov hauv kev lag luam aviation

Silicon carbide yog tsim los rau hauv silicon carbide fiber ntau, silicon carbide fiber ntau yog siv los ua cov ntaub ntawv kub thiab cov khoom siv ntxiv, cov ntaub ntawv kub resistant muaj xws li cov ntaub ntawv tiv thaiv tshav kub, kub resistant conveyor siv, lim ntaub rau kub kub gas los yog molten hlau. Cov khoom siv no muaj qhov sib txawv ntawm qhov dav (band qhov dav dav dua 2.2ev), thermal conductivity siab, siab tawg hluav taws xob, hluav taws xob tsis kam, siab electron saturation tus nqi thiab lwm yam ntxwv, haum rau kub, siab zaus, hluav taws xob tsis kam. thiab cov khoom siv hluav taws xob siab ntau lawm. Tsim kom muaj kev sib raug zoo thiab sib koom tes hauv kev cob qhia cov neeg ua haujlwm thiab kev tshawb fawb thiab kev tsim kho technology; Txhim khu kev sib txuas lus ntawm kev lag luam, tshwj xeeb tshaj yog koom nrog kev sib pauv hloov pauv thoob ntiaj teb, txhawb kev txhim kho theem ntawm kev lag luam; Ua tib zoo mloog rau lub tuam txhab lag luam, thiab siv zog los tsim cov khoom muag ntawm lub tuam txhab.

Daim ntawv thov cov thev naus laus zis tshiab thiab cov khoom siv tshiab los ntawm cov tuam txhab tsim hluav taws xob hauv tsev tseem tsawg dhau, thiab cov inverter nrog silicon carbide ua lub zog hluav taws xob tau pib siv ntau ntau. Kev ua haujlwm sab hauv ntawm silicon carbide yog qhov me me, thiab qhov ua tau zoo tuaj yeem siab heev, qhov hloov pauv tuaj yeem ncav cuag 10K, thiab LC cov ntxaij lim dej thiab lub tsheb npav tuaj yeem cawm tau.

Daim ntawv thov hauv cheeb tsam semiconductor

Silicon-carbide ib-dimensional nanomaterials yuav tsum yog ib feem tseem ceeb ntawm lub thib peb tiam ntawm wide-band gap semiconductor cov ntaub ntawv vim hais tias ntawm lawv cov microscopic morphology thiab siv lead ua qauv, uas ua rau lawv muaj ntau tshwj xeeb zoo heev functions thiab ntau nthuav daim ntawv thov prospects.
