Hauv N - hom semiconductor , cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P - hom semiconductor , qhov yog feem ntau cov cab kuj thiab electrons yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration.

Ib yam li ntawd, nws tau nug, qhov txawv ntawm n hom thiab p hom khoom semiconductor yog dab tsi?

Cov sib txawv n - hom thiab p - hom ntaub ntawv yog impurities los yog dopants. Ob leeg thiab p yam yog Cov khoom siv semiconductor uas yog 99.99+ % tib yam. - yam khoom muaj qee yam ntawm nws cov khoom siv atom hloov nrog lwm cov atoms uas muaj ib qho hluav taws xob ntxiv.

Tsis tas li ntawd, dab tsi yog n hom semiconductor? Ib N - hom semiconductor yog a hom ntawm cov khoom siv hauv electronics. Nws yog tsim los ntawm kev ntxiv ib qho impurity rau ib tug ntshiab semiconductor xws li silicon lossis germanium. Cov impurities siv tej zaum yuav yog phosphorus, arsenic, antimony, bismuth los yog lwm yam tshuaj. Lawv yog hu ua pub dawb impurities.

Hais txog qhov no, dab tsi yog p hom thiab n hom semiconductor?

p - hom thiab n - hom cov ntaub ntawv yooj yim semiconductors , xws li silicon (Si) lossis germanium (Ge), nrog atomic impurities; tus hom ntawm impurity tam sim no txiav txim qhov hom ntawm semiconductor.

Dab tsi yog qhov txawv ntawm intrinsic thiab extrinsic semiconductors?

Cov Qhov sib txawv ntawm intrinsic thiab extrinsic semiconductor yog tias Intrinsic semiconductors yog daim ntawv dawb huv ntawm semiconductor cov ntaub ntawv. Qhov twg Extrinsic semiconductors yog impure semiconductor tsim los ntawm kev ntxiv ib qho impurity rau ib tug ntshiab semiconductor.
