When considering the material between source and drain, what are two basic types of field-effect transistors (FET)?
- ASilicon and germanium
- BGallium and arsenide
- CN channel and P channel
- DNPN and PNP
Correct answer: C — N channel and P channel. From the official ISED question bank, verified word for word.
Why
Field-effect transistors are sorted by the type of charge carriers flowing between the source and drain, which creates either an N channel or a P channel. The full explanation — and one for every question — is in Pro.
