Metallic silicon yog ib hom metallurgical raw khoom uas muaj qhov kub thiab txias tsis kam thiab kev ua haujlwm zoo hauv kev tsim cov khoom siv semiconductor. Hlau silicon hmoov yog cov khoom siv hmoov ua tiav los ntawm cov hlau silicon. Qhov zoo ntawm cov hlau silicon hmoov tau los ntawm cov txheej txheem ntau lawm kuj txawv. Ntxiv rau cov hmoov hlau silicon hmoov, kuj tseem muaj qee yam khoom siv hauv kev tsim cov hmoov hlau silicon hmoov. Txoj kev twg los txais yuav nyob ntawm qhov xwm txheej tiag tiag. Yog li dab tsi yog cov txheej txheem ntawm cov hlau silicon hmoov?
Txoj kev npaj ntawm cov hmoov hlau silicon hmoov yog qhov yooj yim thiab yooj yim, thiab cov txheej txheem kev npaj kuj yooj yim heev thiab nkag siab yooj yim. Tom qab ib co coarse silicon hmoov yog dispersed, nws yog pub rau hauv lub plasma arc nrog inert gas thiab rhuab tam sim ntawd, yog li ntawd cov coarse silicon hmoov instantly evaporates rau hauv silicon vapor ntawm qhov kub thiab txias, thiab ces cov silicon vapor nkag mus rau hauv qhov chaw txias. thiab condenses rau hauv nano-scale metallic silicon. liab.
Pob milling txoj kev: Siv cov kev sib txhuam loj loj uas tsim los ntawm kev sib hloov thiab kev sib cuam tshuam ntawm cov khoom, cov khoom siv silicon loj yog hauv av rau hauv cov hmoov nanoscale. Cov hlau silicon hmoov tsim los ntawm lub pob milling txoj kev muaj cov ntsiab lus impurity siab, particle loj tis tsis tuaj yeem tswj tau zoo, thiab tom qab ua tiav yog cumbersome.
Tshuaj vapor deposition txoj kev: nyob rau hauv qhov kev txiav txim ntawm lwm lub zog xws li tshav kub, microwave, laser, plasma, thiab lwm yam Silane decomposes rau hauv silicon thiab hydrogen nyob rau hauv high hydrogen dilution tej yam kev mob thiab sai condenses nyob rau hauv ib tug roj theem ib puag ncig los npaj nanosilica hmoov.
