Lub peev xwm ntawm ib yam khoom kom dhau qhov hluav taws xob tam sim no hu ua conduction. Cov hlau sib txawv muaj cov khoom sib txawv, feem ntau cov nyiaj muaj qhov zoo tshaj plaws conductivity, ua raws li tooj liab thiab kub. Solid-state conduction yog hais txog kev tsiv mus nyob deb ntawm electrons lossis ions nyob rau hauv ib qho khoom nyob rau hauv qhov kev txiav txim ntawm lub teb hluav taws xob, feem ntau yog tus nqi thauj khoom, xws li: electron conductor, uas ua hluav taws xob feem ntau nrog cov khoom siv hluav taws xob; Conductivity ntawm tus tswv tsev; thiab sib xyaw conductors, uas muaj ob qho tib si cab kuj electrons thiab ions. Tsis tas li ntawd, qee qhov xwm txheej hluav taws xob tsis yog tshwm sim los ntawm cov neeg nqa khoom tsiv teb tsaws, tab sis cov khoom polarization tshwm sim los ntawm hluav taws xob, xws li dielectric phenomena thiab cov khoom siv dielectric.
Feem ntau, hlau, semiconductors, electrolytes, yaj electrolytes thiab qee cov hlau tsis muaj hlau tuaj yeem ua hluav taws xob. Cov hluav taws xob conductivity ntawm cov khoom uas tsis yog electrolytes nyob ntawm seb muaj pes tsawg tus electrons dawb nyob rau hauv nws atomic txheej plhaub thiab nws cov qauv siv lead ua. Piv txwv li, cov hlau muaj cov khoom siv hluav taws xob ntau, thiab cov hlau tsis muaj hlau feem ntau tsis yooj yim rau hluav taws xob vim lawv cov hluav taws xob tsawg tsawg. Pob zeb diamond muaj hluav taws xob conductivity, uas muaj feem xyuam rau qhov sib txawv ntawm nws cov qauv siv lead ua. Electrolytes ua hluav taws xob vim cov anions tsim thaum cov ionic compounds yaj los yog yaj, thiab yog li ua hluav taws xob.
Raws li cov hlau conductive uas tsis yog nyiaj, tooj liab feem ntau yog siv rau hauv cov cables tseem ceeb thiab cov phaj conductive. Qhov siab dua qhov purity, qhov zoo dua qhov conductivity.
Raws li 3D ntxeem tau cov khoom siv ua los ntawm tooj liab ua raw khoom, qhov zoo ntawm tooj liab ua npuas ncauj thiab siab dua cov cuab yeej tsim khoom, siab dua qhov purity ntawm tooj liab, thiab qhov zoo dua cov hluav taws xob conductivity raws li.
Qhov hluav taws xob conductivity ntawm hlau ua npuas ncauj yog txuam nrog hluav taws xob conductivity ntawm tej hlau. Feem ntau, muaj cov oxides uas tsis zoo conductivity nyob rau saum npoo ntawm lub hauv paus hlau, thiab muaj ntau yam phem conductors ntawm hluav taws xob nyob rau hauv lub ntxeem tau qauv ntawm foamed hlau, yog li ntawd lub conductivity ntawm foamed hlau tsis zoo li ntawd. ntawm cov hlau loj.
Nyob rau hauv qhov sib npaug ntawm cov hluav taws xob conductivity thiab 3D ntxeem tau qauv, ob peb qauv tau tsim los rau hauv tus account ob qho tib si. Nyob rau hauv daim ntawv thov, txawm hais tias cov hluav taws xob conductivity tsis zoo li cov khoom ntshiab tooj liab cables thiab nplooj ntawv, qhov zoo ntawm 3D ntxeem tau qauv yog tag nrho exerted. Piv nrog cov khoom tsis yog cov khoom siv tooj liab, cov hluav taws xob conductivity ntawm tooj liab ua npuas ncauj zoo dua.
