What is the name given to an impurity atom that adds holes to a semiconductor crystal structure?
- A.Insulator impurity
- B.N-type impurity
- C.Acceptor impurity (correct answer)
- D.Donor impurity
WhyAn impurity atom that adds holes to a semiconductor crystal structure is called an acceptor impurity. An impurity atom that adds holes to a semiconductor crystal is called an acceptor impurity, since it "accepts" an electron from a neighboring bond, leaving a hole behind, the doping mechanism that creates P-type material, answer C. "Insulator impurity" isn't a real term, and N-type and donor impurities describe the opposite process, adding electrons rather than holes.
