Un semi-conducteur est dit dopé lorsqu'on lui a ajouté une faible quantité :
- Ade protons
- Bd'ions
- Cd'électrons
- Dd'impuretés
Correct answer: D — d'impuretés. Question tirée de la banque officielle d'ISDE.
Why
Doping happens when tiny amounts of impurities are mixed into a pure semiconductor like silicon to change how well it conducts electricity. The full explanation — and one for every question — is in Pro.
