Question

What is carrier drift?

Answer 1

1. Carrier Drift is, charged particle motion in response to an applied electric field.
2. When an electric field is applied across a semiconductor, the carriers start moving, producing a current.
3. The positively charged holes move with the electric field, whereas the negatively charged electrons move against the electric field.
4. The motion of each carrier can be described as a constant drift velocity.
5. The carrier drift is what causes the drift current in a semiconductor.
6. Drift current is generated by charge carriers moving under the influence of an external electric field.
