Muaj pes tsawg tus nqi silicon npaum li cas rau ib tuj?
Muaj silicon yog cov khoom siv tseem ceeb thiab tau siv dav hauv cov khoom siv hluav taws xob, photovoltacs, tshuaj lom neeg thiab lwm yam tshuaj. Tus nqi ntawm kev lag luam silicon cuam tshuam los ntawm ntau yam xws li kev ua lag luam thiab kev thov, cov txheej txheem khoom siv raw, yog li tus nqi yuav ua tiav. Feem ntau hais lus, tus nqi ntawm kev lag luam silicon feem ntau yog nruab nrab ntawm US $ 1, 000 thiab US $ 2 {3}} ib tuj.

Ua ntej tshaj plaws, kev ua lag luam thiab kev thov yog ib qho tseem ceeb cuam tshuam rau cov nqe ntawm kev lag luam silicon. Nrog rau kev txhim kho sai ntawm cov hluav taws xob kev lag luam, kev lag luam photovoltaic, thiab lwm yam. Ib qho ntxiv, qee lub tebchaws thiab cov cheeb tsam muaj qhov loj rau kev lag luam silicon, uas tseem muaj qee yam cuam tshuam rau hauv ntiaj teb nqe ntawm kev lag luam silicon.
Thib ob, tus nqi ntawm raw khoom yog lwm qhov tseem ceeb cuam tshuam rau tus nqi ntawm kev lag luam silicon. Cov khoom siv raw ntawm kev lag luam silicon yog silicon dioxide, thiab tus nqi ntawm silicon dioxide cuam tshuam los ntawm ntau yam xws li tus nqi ore thiab lub zog hnav. Yog tias tus nqi ntawm raw cov ntaub ntawv nce, nws yuav inevitably ua rau nce nyob rau hauv tus nqi ntawm kev lag luam silicon, thiab vice versa.
Ib qho ntxiv, cov txheej txheem ntau lawm yuav muaj kev cuam tshuam rau tus nqi ntawm kev lag luam silicon. Nrog kev nce qib nruam ntawm thev naus laus zis, kev txhim kho ntawm cov txheej txheem ntau lawm tuaj yeem txo cov silicon, yog li txo tus nqi ntawm kev lag luam silicon. Nyob rau tib lub sijhawm, qhov tshwm sim ntawm qee cov txheej txheem ntau yam tshiab tseem yuav txhawb kev ua lag luam kev ua lag luam, yog li tsav tsheb cia cov nqi silicon.
Feem ntau, tus nqi ntawm kev lag luam silicon cuam tshuam los ntawm ntau yam, thiab nws tus nqi yuav hloov pauv. Tab sis raws li ib qho tseem ceeb cov khoom siv tseem ceeb, tus nqi ntawm kev lag luam silicon yuav tswj hwm lub nrawm nrawm rau lub sijhawm ntev. Txawm li cas los xij, qhov xwm txheej tshwj xeeb ntawm tus nqi tseem yuav tsum tau txheeb xyuas raws li cov xwm txheej tshwj xeeb ntawm lub sijhawm sib txawv thiab thaj av.
