- MCQ
Statement\(-I :\) By doping silicon semiconductor with pentavalent material, the electrons density increases. Statement\(-II :\) The \(n-\)type semiconductor has net negative charge. In the light of the above statements, choose the most appropriate answer from the options given below:
Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) Statement\(-I\) is true but Statement\(-II\) is false.
Step-by-step Solution
Detailed explanation
Pentavalent activities have excess free \({e}^{-}\)
So \({e}^{-}\)density increases but overall semiconductor is neutral.
