The conductivity of silicon can be increased by introducing trace quantities of another element as an impurity in a process referred to as doping. Which element listed below when introduced as an impurity into silicon would provide a n-type conductor?

Question

Quizplus · Accepted Answer

Phosphorus (P) is a group V element, which means it has one extra electron compared to silicon. When phosphorus is introduced as an impurity into silicon, it creates an excess of electrons, turning silicon into an n-type conductor.
