Tsis ntev los no, Pawg Tshawb Fawb ntawm xibfwb Qiu Minestre tau tsim cov kev daws teeb meem tshiab rau cov teeb meem thermal drift high-fais fab ua laser.
Cov ntawv muaj feem cuam tau luam tawm hauv cov ntaub ntawv siab nyob hauv qab ntawm cov npe ntawm "4H-Sic hlauens: mitigating thermal drift nyhuv laser iradiation".
Piv nrog cov ntsiab lus lag luam ua lag luam, no lub superlens tswj kev ua txawv-kev ua kom pom tseeb thaum qhia tau zoo heev thermal ruaj khov. Nws tuaj yeem tswj kev ua tau ruaj khov nyob rau hauv lub sijhawm ntev-fais fab laser iradiation thiab yuav luag tsis muaj kev cuam tshuam los ntawm kev nqus thermal. Qhov kev ua tau zoo no yog vim cov khoom zoo tshaj plaws ntawm 4H-cov ntaub ntawv hloov chaw, suav nrog kev ua haujlwm siab dua thiab kos cov khoom siv zoo rau kev ua haujlwm siab saib.
Cov superlens tshiab ua rau siv cov khoom siv thermal siab thiab cov khoom poob qis, thiab yog li tau txais kev vam khom rau ntawm cov tshuab cua txias. Qhov kev hloov thev naus laus zis no tsuas yog muab kev txhawb nqa kom tseem ceeb rau kev tsim cov chaw tsim khoom, cov kev tshawb nrhiav tshiab rau ntau qhov kev ua tau zoo rau kev ua qhov yog thiab qhov zoo. 4H-SIC Suplens yuav ua lub luag haujlwm tseem ceeb thiab muab cov kev daws teeb meem zoo tshaj plaws rau cov kev siv hluav taws xob high zog.
Ua ntej lawm, Tsev Kawm Ntawv Westlake tseem tshaj tawm hauv kev sib tsoo hauv Silicon Carrated thev naus laus zis Laser Laser Laser Laser Ultra-loj Silicon Carbide substrates. Lub laser sau ntau pua pua lab ntawm cov ntsiab lus zoo "blasting cov ntsiab lus" sab hauv cov khoom siv kom ua tiav kev hloov txheej ntawm txheej ingot los ntawm txheej. Qhov ceev ntawm daim hlais yog txhim kho piv rau cov kev tsoos ib txwm txiav, thiab cov khoom poob yog txo los ntawm 50%.
Ob txoj kev sib tawg no qhia tau tias Westlake University yog nyob rau hauv kev tshawb fawb thoob ntiaj teb, thiab muab cov ntaub ntawv tshawb fawb high zog, thiab kev tsim kho cov khoom siv nyiaj txiag, kev lag luam hauv lub zog thiab kev lag luam hluav taws xob.
