What type of semi-conductors is produced when silicon is doped with arsenic?

Text Solution

Verified by Experts

Silicon has 4 valence electrons while arsenic has 5 valence electrons. Doping silicon with arsenic leads to extra electrons which are free to conduct electric current. This result in n-type semi-conductors.
