Notes

Subscripts $n$ and $p$ or $-$ and $+$ are often used to denote electrons and holes, respectively. $n_{n}$ and $n_{p}$ are also used for electron densities, and $p_{n}$ and $p_{p}$ for hole densities, in $n$ -type and $p$ -type regions, respectively, of a $n$ - $p$ junction.

Les indices $n$ et $p$ ou $-$ et $+$ sont souvent utilisés pour désigner respectivement les électrons et les trous. $n_{n}$ et $n_{p}$ sont aussi utilisés pour les densités électroniques, et $p_{n}$ et $p_{p}$ pour les densités de trous, respectivement dans les régions de type $n$ et de type $p$ d'une jonction $n$ - $p$ .
