Answer & Solution
Answer: Option B
Solution:
Selenium is an
intrinsic semiconductor.
An intrinsic semiconductor is one that is pure and contains no significant dopants or impurities. In the case of selenium, it is an intrinsic semiconductor when it is in its pure form. Intrinsic semiconductors have equal numbers of electrons and holes, allowing for the flow of current under certain conditions.
Extrinsic semiconductors, on the other hand, are those that have been intentionally doped with impurities to alter their electrical properties. These can be further categorized into N-type and P-type semiconductors based on the type of doping introduced.
Therefore, the correct spelling of the term is
intrinsic, making Option B the correct
