Cov kab hluav taws xob yog cov kab hluav taws xob hluav taws xob uas cov hluav taws xob tuaj yeem dhia mus rau hauv lub valence band thaum zoo siabThaum cov electrons nyob hauv cov orbitals, lawv muaj zog txaus txav. dawb do hauv cov khoom. Qhov kev txav ntawm electrons no tsim cov hluav taws xob tam sim no.
Puas electrons dawb nyob rau hauv lub conduction band?
Tsis tas li ntawd, cov electrons nyob rau hauv lub conduction band yog dawb txav mus los nyob ib ncig ntawm cov khoom nrog me ntsis tsis kam, thaum nyob rau hauv lub valence band cov electrons feem ntau khi rau niam txiv atom / molecule, tab sis lawv muaj qee qhov kev ywj pheej, tsuas yog tsis ntau npaum li cov hluav taws xob conduction. Saib valence band ntawm wikipedia.
Koj ua li cas thiaj txiav txim siab tus naj npawb ntawm cov electrons hauv ib pawg conduction?
Tag nrho cov xov tooj ntawm cov hluav taws xob hauv cov khoom siv hluav taws xob, N cb, tuaj yeem tau txais los ntawm kev sib xyaw ua haujlwm saum toj no los ntawm hauv qab ntawm cov khoom siv hluav taws xob nce mus..
Dab tsi yog conduction electron?
[kən′dək·shən i′lek'trän] (khoom lub xeev physics) Ib qho hluav taws xob hauv cov khoom siv hluav taws xob, qhov twg nws muaj kev ywj pheej txav los ntawm hluav taws xob. field. Kuj tseem hu ua lub plhaub sab nraud electron; valence electron.
Yuav ua li cas yog hlau conduction electrons?
Cov conduction electrons nyob rau hauv ib lub hlau yog non-localized(piv txwv li, lawv tsis khi rau ib qho tshwj xeeb atoms). Hauv cov pa hlau, txhua lub atom txhawb nqa ib qho electron. Cov conduction electrons tuaj yeem, yog li, raug kho raws li cov roj zoo tagnrho. …
