Doping of a semiconductor (with small impurity atoms) generally changes the resistivity as follows. (a) Decreases (b) Does not change (c) May increase or decrease depending on the dopant (d) Increase

Answer: (a). Doping adds many extra charge carriers to the semiconductor. More carriers mean higher conductivity, so resistivity decreases. So the answer is (a) Decreases.

Doping of a semiconductor (with small impurity atoms) generally changes the resistivity as follows.

Show answer and solution

Answer: (a)

Doping adds many extra charge carriers to the semiconductor.
More carriers mean higher conductivity, so resistivity decreases.
So the answer is (a) Decreases.
