[...] l'énergie cinétique des électrons qui est faible à température normale, augmente dans des proportions considérables avec la température. Elle peut pour certains électrons atteindre une valeur suffisante pour leur permettre de franchir la barrière de potentiel. Cette émission est appelée «thermoélectronique» car l'énergie d'extraction est d'origine thermique. 7, record 3, French, - %C3%A9mission%20thermo%C3%A9lectronique
