Notes

EN

Indices " n " and " p " denote negative and positive charge carriers, respectively. Positive charge carriers can also be holes.

FR

Les indices « n » et « p » désignent respectivement les porteurs de charge négative et positive. Les porteurs de charge positive peuvent aussi être des trous.
