JEE Mains · Physics · STD 12 - 14. Semicondutor electronics
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:
- A Statement\(-I\) is true but Statement\(-II\) is false.
- B Statement\(-I\) is false but Statement\(-II\) is true.
- C Both Statement\(-I\) and Statement\(-II\) are true.
- D Both Statement\(-I\) and Statement\(-II\) are false.
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.
