When the temperature of an extrinsic semiconductor is increased, the pronounced effect is on_________________?
Correct answer: B. Minority carriers
- A. Junction capacitance
- B. Minority carriers
- C. Majority carriers
- D. None of the above
Explanation
With increasing temperature, thermally generated minority carriers increase markedly, while the majority-carrier concentration in an extrinsic semiconductor remains approximately set by the dopant concentration over the normal range. Hence the pronounced effect is on minority carriers.
