Question

Why is there an increase in conductivity when silicon is doped with phosphorus?

Answer 1

There is an increase in conductivity when Silicon is doped with Phosphorus because : Si doped with P becomes N type semiconductor. ... In that four valence electrons will be used for bonding with Si and fifth electron serves to conduct electricity
