JEE MAIN - Physics (2021 - 26th August Morning Shift - No. 20)
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 :
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 :
Statement - I is true but Statement - II is false.
Statement - I is false but Statement - II is true.
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
توضیح
Pentavalent activities have excess free e$$-$$, so e$$-$$ density increases but overall semiconductor is neutral.
