Dab tsi yog cov khoom siv zoo tshaj plaws rau hnub ci vaj huam sib luag?

Lub zog tsim hluav taws xob ntawm monocrystal silicon yuav siab, tab sis lub teeb tsis muaj zog yuav ua rau me ntsis zuj zus, feem ntau siv ntau polycrystalline, thiab yog tias koj tsis nkag siab lub rooj tsavxwm, nws raug nquahu kom koj xaiv lub hom loj, lossis yuav tsis muaj txiaj ntsig. board, uas yuav tsis siv ob peb xyoos, tab sis lub hom loj yog feem ntau tsawg dua thiab tsis muag, koj tuaj yeem nrhiav tau lub tuam txhab tshwj xeeb uas tau muab faib ua ke, uas tau lees paub ntau dua.

Cov ntaub ntawv dab tsi yog siv los ua cov hnub ci vaj huam sib luag? Qhov no yog ib qho teeb meem koom nrog hauv semiconductor physics.

Cov khoom yuav muab faib ua conductors, semiconductors thiab insulators raws li lawv cov hluav taws xob conductivity.

Nyob rau hauv cov nqe lus ntawm lub internal qauv ntawm cov teeb meem, lub conductivity ntawm teeb meem yog tshwm sim los ntawm lub zog ntawm electrons.

Yog hais tias tag nrho cov theem ntawm lub zog nyob rau hauv cov khoom yog sau los ntawm electrons, ces cov electrons tsis muaj chaw txav, thiab lawv yuav tsis ua hluav taws xob, uas yog, ib tug insulator.

Yog hais tias ib feem ntawm lub zog theem nyob rau hauv cov khoom yog khoob, thiab lwm qhov yog sau los ntawm electrons, ces, nyob rau hauv lub xeev tsis muaj kev cuam tshuam sab nraud, cov electrons yuav nyob rau hauv lub hauv av xeev, uas yog, lub xeev uas muaj lub zog qis tshaj. , sib piv rau qib qis zog, ces lub zog siab yog qhov khoob. Thaum muaj cov khoom siv hluav taws xob sab nraud, cov khoom siv hluav taws xob nyob rau theem qis zog nqus lub zog thiab hloov mus rau qib siab zog, thiab kev txav ntawm electrons tshwm sim. Nws muaj hluav taws xob conductivity.

Lub hnub ci hlwb yog ua los ntawm cov khoom siv hluav taws xob zoo nkauj semiconductor, feem ntau zoo li siv cov tshuaj silicon.

Lub hnub ci tiag tiag txawv ntawm qhov peb nco qab. Feem ntau, tib neeg xav tias nws yuav tsum yog qhov ci ntsa iab heev, tab sis qhov tseeb, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm ntxhib, vim qhov kev siv ntawm lub teeb yog qhov tsawg.
