Selenium is __________ semiconductor?
Correct answer: B. intmisic
- A. extrnisic
- B. intmisic
- C. N-type
- D. P-type
Explanation
Pure selenium is classified as an intrinsic semiconductor because its conductivity arises from the material itself rather than from deliberately added impurities. Doping can produce extrinsic, n-type, or p-type selenium, but that is not stated here.
