Thermoelectric cov nyhuv
Cov nyhuv thermoelectric muaj cov macroscopic hluav taws xob dipole lub sij hawm tshwm sim los ntawm qhov tshwm sim polarization, thiab cov khoom siv hluav taws xob nrog qhov loj thermal nthuav coefficient yog hu ua cov siv lead ua thermoelectric. Cov pyroelectric siv lead ua nyob rau hauv lub xeev qhov sib txawv ntawm cov polarization muaj tus nqi them tsim los ntawm qhov pom ntawm qhov chaw ntawm qhov zoo thiab qhov kawg ntawm hluav taws xob dipole lub sijhawm, tab sis nws tsis qhia lub cuab yeej them nqi vim yog adsorption ntawm ions sib txawv hauv huab cua Cov. Thaum qhov kub hloov, qhov ntim ntawm lub thermoelectric siv lead ua hloov pauv qhov tseem ceeb, uas ua rau muaj qhov hloov pauv qhov tseem ceeb ntawm cov polarization siv, rhuav tshem hluav taws xob nruab nrab ntawm lub ntsej muag, thiab ntau dhau tawm adsorbed rau saum npoo yuav tso tawm. Qhov tshwm sim no yog hu ua cov nyhuv thermoelectric. Ob qho tib si artificially polarized ferroelectrics thiab xaiv cov xim muaj cov nyhuv thermoelectric. Lub thermoelectric nyhuv tau siv nyob rau hauv infrared nrhiav thiab thermal ntsuas cov thev naus laus zis.
