[originally after Italian effetto Zener (1948 in the paper referred to in quot. 1949)] the reduction in electrical resistance across the p–n junction of a semiconductor diode under a reverse voltage that occurs as a result of the quantum tunnelling of valence electrons to the conduction band, allowing substantial current to flow in the reverse direction.The Zener effect occurs at a well-defined voltage threshold. This is in contrast with the Avalanche effect, which takes place at a higher reverse voltage, with a less precipitous change in resistance.extracted from Zenern.2< as lemmas |
