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 :
Select the correct option:
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.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Pentavalent activities have excess free e–
So e– density increases but overall semiconductor is neutral.
