In the given 15 group elements which is used as a doping agent in semiconductors?
Nitrogen
Arsenic
Phosphorus
Antimony
Phosphorus is commonly used as a doping agent in semiconductors due to its ability to donate an extra electron, which creates an excess of negative charge in the semiconductor material. Hence option 3 is the correct answer.
Option(1) Nitrogen is not commonly used as a doping agent in semiconductors. Hence option 1 is incorrect.
Option(2) Arsenic is not commonly used as a doping agent in semiconductors. Hence option 2 is incorrect.
Option(4) Antimony is not commonly used as a doping agent in semiconductors. Hence option 4 is incorrect.
