Hauv n-hom semiconductors lawv yog electrons, thaum nyob rau hauv p-hom semiconductors lawv yog qhov. Cov neeg nqa khoom tsawg dua yog hu ua cov neeg nqa khoom tsawg; nyob rau hauv n-hom semiconductors lawv yog qhov, thaum nyob rau hauv p-hom semiconductors lawv yog electrons.
Cov khoom thauj tam sim no nyob rau hauv semiconductors yog dab tsi?
Dab tsi yog cov khoom thauj tam sim no hauv semiconductors? Nqe lus piav qhia: Electrons thiab qhovyog ob lub thauj khoom tam sim no hauv semiconductors. Cov hluav taws xob tsis zoo raug them thaum lub qhov raug them zoo. Lawv txav mus rau qhov tam sim no nyob rau hauv lub semiconductor.
Dab tsi yog cov khoom thauj khoom hauv semiconductors electrons thiab qhov?
Holes thiab electrons yog ob hom kev them nqi thauj khoom ua lub luag haujlwm rau tam sim no hauv cov khoom siv hluav taws xob. Lub qhov yog qhov tsis muaj hluav taws xob nyob rau hauv ib qho chaw tshwj xeeb hauv ib qho atom. Txawm hais tias nws tsis yog ib qho khoom siv lub cev nyob rau hauv tib lub ntsiab lus raws li ib qho hluav taws xob, lub qhov tuaj yeem dhau los ntawm atom mus rau atom hauv cov khoom siv semiconductor.
Yuav ua li cas them cov cab kuj tsim nyob rau hauv semiconductors?
Cov kab ke yog txheej txheem uas cov khoom siv hluav taws xob-qhov yog tsim los ntawm cov khoom siv hluav taws xob zoo siab los ntawm valence band ntawm semiconductor mus rau cov khoom siv hluav taws xob, yog li tsim lub qhov hauv qhov valence band.
Tus nqi thauj khoom hauv semiconductors 1 point yog dab tsi?
Dab tsi yog cov khoom thauj hauv cov khoom siv hluav taws xob? Kev daws: Hauv cov conductors, electrons yog cov khoom thauj. Tab sis nyob rau hauv semiconductors, ob qho tib si electrons thiab qhovyog cov nqa khoom thiab yuav koom nrog hauv kev coj ua.
