Raws li qhov kev thov kom nrawm dua, me dua, thiab ntau lub zog hluav taws xob ua kom muaj zog, piv txwv los ntawm silicon mus rau cov khoom lag luam siab tshaj plaws ntawm kev xauv cov kev ua tau zoo. Cov kws tsim khoom yog tam sim no tshawb xyuas lwm txoj kev xaiv zoo li gallium nitride (Gan), siic), thiab kev hloov pauv ntawm graphene thiab kev hloov tsheb hlau Dichalcogenides (TMDS). Cov ntaub ntawv no yuav tau cog lus rau kev rov suav ua lej, cov hluav taws xob sib txuas lus, daws cov kev txwv ntawm kabmob Ai, hluav taws xob (EVS), thiab tom ntej-gener.
Silicon cov kev txwv thiab lub laub rau lwm txoj
Silicon, tus qaum qaum ntawm cov khoom siv hluav taws xob niaj hnub, yog nyob ze nws txoj kev txwv lub cev. Kev sib tw hauv lub hwj chim ntom ntom, thermal kev tswj hwm, thiab hloov ceev tau ua cov bottenecce tseem ceeb rau cov thev naus laus zis. AI workdle, piv txwv tias, yuav tsum tau cov txheej txheem uas txo qis zog poob ntawm cov kev sib xyaw ua ke, thaum Evs xav tau lub zog hluav taws xob. Ib yam li ntawd, 5G thiab dhau ntawm cov neeg xav tau semiconductors uas ua haujlwm ntseeg tau ntawm millimeter-yoj ntau zaus. Cov kev xav tau no tau tsav tsheb txoj kev lag luam rau dav-bandgap thiab ultra-nyias cov ntaub ntawv engineered los surpass Silicon lub peev xwm.
Gallium nitride (GAN): Powering high-zaus pem hauv ntej
Gan tau tawm los ua tus frontrunner hauv kev siv lub zog muaj zog thiab kev siv zog ntau zaus. Nws cov bandgap dav siv hluav taws xob kev mus txog li 10x siab dua li silicon, tso cov khoom siv kom nrawm dua nrog kev siv hluav taws xob tsawg dua. Qhov no ua rau gan zoo tagnrho rau radiofrequency (RF) hauv 5G puag ncig thiab satellite sib txuas lus, uas yog qhov ntsuas kev ncaj ncees thiab kev ua tau zoo yog qhov tseem ceeb.
Nyob rau hauv lub hwj huam hluav taws xob, Gan cov thermal zoo tshaj thermal thiab vettage kam rau txo qhov xav tau rau cov tshuab txias kom txias. Qhov no yog hloov rau EVS, qhov twg Gan-based chargers thiab inverters tuaj yeem slash lub sij hawm them nyiaj ua haujlwm. Cov chaw zov me me, ib yam nkaus, tau txais txiaj ntsig los ntawm GAN lub peev xwm los tuav lub siab ua kom muaj zog hauv kev cog lus hneev, txo cov nqi kev ua haujlwm thiab cov kab mob carbon.
Silicon Carbide (Sic): Revolutizing High-Voltage Systems
Sic tau txais kev nce qib hauv cov ntawv thov uas xav tau kev ua haujlwm hnyav nyob rau hauv huab. Nrog rau qhov tawg yuam peb ntau dua li silicon, sic sicicon, sic semiconductors excel nyob rau hauv lub siab-voltage ib puag ncig thiab kev tsav tsheb tractters thiab muaj lub cev muaj zog tsav tsheb. Lawv lub peev xwm los ua haujlwm ntawm kev nce qhov kub kom txo tau cov nqi tsis ua haujlwm nyob rau hauv Harsh chaw, los ntawm Aerospace cov khoom siv rau hnub ci hluav taws xob.
Sic qhov qis dua kev ua kom tiav kuj ua rau nws lub pob zeb ua kom txuas lub zog indressure txuas ntxiv. Nyob rau hauv lub hnub ci inverters thiab cua tshuab hloov pauv, cov khoom siv puab tsawg zuj zus tuaj lub zog siv hluav taws xob, ua kom muaj zog ntawm cov zis tawm. Raws li lub ntiaj teb grids tshiab, sic yog poised kom ua si ib tug pivotal lub luag hauj lwm hauv kev ua kom muaj zog sib kis tau, lub zog ntev.
2D Cov Khoom Siv: Cov atomic-teev kiv puag ncig
Dhau ntawm cov neeg sib xyaw ua ke, 2d cov ntaub ntawv zoo li graphene thiab tmps yog rov ua dua yog dab tsi ua tau ntawm qib atomic. Graphene cov hluav taws xob tshwj xeeb, ua khub nrog cov khoom siv tshuab, qhib cov qhov rooj kom muaj ultra-nyias, foldable electronics thiab tshaj tawm cov khoom siv txawb. Lub caij no, tmds xws li molybdenum discacting, ua rau lawv zoo rau cov khoom siv tsis muaj zog zoo li cov ntaub ntawv tsis yooj yim thiab lub teeb ci ntsa iab (coj).
Cov ntaub ntawv no tshwj xeeb tshwj xeeb rau kev xa ntawv-Moore txoj cai sau. 2D semiconductors tuaj yeem pab pawg, 3D-sib xyaw ua ke uas bypes site silicon cov scriping txwv tej zaum yuav underpin breaks nyob rau hauv Quantum xam thiab neural tess.
Kev tsim cov nyom thiab kev lag luam evolution
Txawm hais tias lawv muaj peev xwm, hloov mus rau cov ntaub ntawv tsis-silicon nthuav tawm hurdles. Gan thiab Sic yuav tsum muaj cov txuj ci tshwj xeeb, xws li heteropitaxial kev loj hlob ntawm tsis yog haiv neeg substrates, uas raises cov nqi ntau lawm. Lub caij no, synthesizing yam-dawb 2D cov ntaub ntawv ntawm nplai tseem yog cov tswv yim ua ntej. Cov thawj coj hauv kev ua lag luam tau hais txog cov teeb meem no los ntawm kev nce qib hauv txheej txheem tshuaj
Muab cov khoom siv saw hlau muaj kev hloov pauv. Investments in substrate production and hybrid manufacturing processes-combining silicon-based infrastructure with novel material integration-are accelerating commercialization. Cov tsoomfwv thiab cov haujlwm ntiav thoob ntiaj teb tau txais kev tshawb nrhiav cov txheej txheem, kom tau cov txheej txheem kev ntseeg siab, kho kho mob, kho mob, thiab kev tiv thaiv cov ntawv thov.
Txoj kev ua ntej: hybrid system thiab cov duab tshiab
Lub neej yav tom ntej yuav pom kev sib xyaw ua ke heterogeneous, qhov twg silicon coexists nrog Gan, Sic, thiab 2D cov ntaub ntawv hauv ntau cov nti modules. Piv txwv li, Ai Accelerators tuaj yeem khub Silicon CMOS logic nrog Gan-based fais fab xa khoom, ua kom zoo dua ob qho tib si sib txawv thiab lub zog ua haujlwm. Ib yam li ntawd, "ntau dua-tshaj-moore" architectures yuav sib txuas nrog graphene interconnects, tsim cov tshuab uas tau ua rau ob qho tib si kev ua haujlwm thiab kav ntev.
Lwm cov neeg ua ntej yog lub convergence ntawm photonics thiab hluav taws xob. 2D Cov ntaub ntawv muaj peev xwm tso tawm thiab kuaj pom lub teeb ntawm cov nanoscale tuaj yeem ua rau muaj kev sib txuas lus kho qhov muag, Drastically txo cov latency hauv cov ntaub ntawv thiab kev ua haujlwm siab ntsuas.
Qhov txav dhau silicon cim ib tshooj hloov pauv hauv Indormative Tshooj nyob rau qib tshiab. Gan, Sic, thiab 2D cov ntaub ntawv tsis yog nce ntxiv kev hloov kho tshiab tab sis cov koom tes ntawm cov ntawv thov tshiab-los ntawm ultra-ceev 6g tes hauj lwm rau tus kheej cov khoom siv. Raws li kev tsim khoom loj thiab hla kev sib koom tes kev lag luam sib koom tes, cov ntaub ntawv no yuav rov ua cov ciaj ciam ntawm cov thev naus laus zis tau nce siab thiab muaj txiaj ntsig. Lub toj roob hauv pes semiconductor yog tsis lo lo lus los ntawm cov kev txwv ntawm ib lub caij; Nws nthuav dav rau hauv cov khoom siv ntau yam uas ua tau zoo thiab muaj peev xwm teev tes ua ke.
