qhia txog:
Hauv kev tsim khoom thiab kev tsim khoom siv, cov txheej txheem txheej nqus tsev yog ib qho thev naus laus zis tseem ceeb uas tau hloov pauv ntau yam kev lag luam. Cov thev naus laus zis siab heev no tso cai rau cov zaj duab xis nyias nyias siv rau ntau qhov chaw, muab cov khoom zoo dua thiab kev ua haujlwm zoo dua. Hauv tsab ntawv blog no, peb yuav kawm tob txog cov txheej txheem txheej nqus tsev, tham txog nws cov ntsiab lus tseem ceeb thiab qhia txog nws ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub no.
Cov txheej txheem txheej txheem nqus tsev yog dab tsi?
Kev txheej txheej nqus tsev yog ib txoj kev tso cov txheej nyias nyias ntawm cov khoom rau ntawm ib lub substrate hauv ib puag ncig tswj tau. Cov txheej txheem no tshwm sim hauv lub chamber nqus tsev thiab siv ntau txoj kev xws li thermal evaporation, sputtering thiab electron beam deposition los siv cov khoom xav tau rau ntawm qhov chaw. Los ntawm kev tshem tawm huab cua thiab lwm yam khoom tsis huv, cov txheej txheem txheej nqus tsev ua kom ntseeg tau tias cov txheej txheej zoo, sib xws uas lo rau lub substrate.
Cov ntawv thov thiab qhov zoo ntawm lub tshuab nqus tsev txheej:
Cov txheej txheem nqus tsev muaj ntau yam thiab sib txawv, nrog rau kev lag luam xws li tsheb, khoom siv hluav taws xob, kho qhov muag thiab txawm tias cov khoom siv hauv tsev tau txais txiaj ntsig los ntawm cov thev naus laus zis no. Piv txwv li, cov txheej nyias nyias uas siv los ntawm txheej nqus tsev tuaj yeem ua rau muaj kev tiv thaiv xeb, kev tiv thaiv kev sib txhuam thiab cov khoom siv kho qhov muag, ua rau cov khoom ruaj khov dua thiab zoo nkauj dua. Tsis tas li ntawd, nws tuaj yeem tso cov txheej tshwj xeeb xws li cov txheej tiv thaiv kev cuam tshuam rau ntawm cov iav, cov txheej cuam tshuam rau ntawm daim iav thiab cov txheej tiv thaiv ntawm cov vaj huam sib luag hnub ci.
Kev ua tau zoo dua thiab kev ua haujlwm zoo dua:
Cov txheej txheem txheej txheej los ntawm lub tshuab nqus tsev ua rau muaj ntau yam khoom siv, suav nrog cov hlau, cov khoom siv av nplaum, cov khoom siv semiconductor, thiab cov polymers. Los ntawm kev xaiv thiab txheej cov ntaub ntawv no kom zoo, cov chaw tsim khoom tuaj yeem kho cov yam ntxwv ntawm cov khoom siv coated kom ua tau raws li cov kev xav tau tshwj xeeb. Cov khoom siv coated los ntawm lub tshuab nqus tsev tuaj yeem ua rau muaj kev ua tau zoo dua ntawm hluav taws xob, kev rwb thaiv tsev, cov khoom siv sib nqus, cov khoom siv optical, thiab txawm tias biocompatibility. Lub peev xwm no los txhim kho kev ua tau zoo thiab kev ua haujlwm tau ua rau kev txheej txheej los ntawm lub tshuab nqus tsev yog ib qho thev naus laus zis tseem ceeb hauv ntau yam lag luam.
Kev nce qib thiab cov qauv yav tom ntej:
Vim muaj kev tsim kho tshiab tas mus li, cov txheej txheem txheej txheej nqus tsev tseem niaj hnub tsim kho, thiab cov thev naus laus zis tshiab thiab cov khoom siv kuj tseem niaj hnub tsim kho. Piv txwv li, pulsed laser deposition (PLD) thiab atomic layer deposition (ALD) sawv cev rau cov thev naus laus zis tshiab uas tso cai rau kev ua kom raug thiab tswj tau cov txheej txheem txheej. Tsis tas li ntawd xwb, peb siv zog los tsim cov khoom siv txheej txheej uas zoo rau ib puag ncig thiab ruaj khov kom tau raws li qhov xav tau ntawm kev tsim khoom uas zoo rau ib puag ncig.
xaus lus:
Cov txheej txheem txheej tshuab nqus tsev tau hloov pauv ntau yam lag luam los ntawm kev ua kom siv tau cov zaj duab xis nyias uas muaj cov khoom zoo dua thiab kev ua haujlwm zoo dua. Txij li kev ua kom lub zog ntawm cov khoom siv hauv tsheb ruaj khov mus rau kev ua kom cov khoom siv hluav taws xob zoo dua, cov txheej txheem txheej tshuab nqus tsev ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub. Qhov cuam tshuam ntawm cov txheej txheem no tsuas yog yuav nthuav dav thaum thev naus laus zis nce qib thiab cov ntaub ntawv tshiab tau tshawb pom, tsav tsheb tsim kho tshiab thiab thawb cov ciam teb ntawm qhov ua tau hauv kev tsim khoom siv.
