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:
Option: 1 Both statement I and Statement II are false.
Option: 2 statement I is true but Statement II is false.
Option: 3 Statement I is false but Statement II is true.
Option: 4 Both Statement I and Statement II are true.
Statement I
By doping silicon semiconductors with pentavalent material.
Statement II
The n-type semiconductor has a net negative charge
Both the statements are true
Hence, the correct option is (4)
