A) Yes
B) No
C) Maybe
D) Information is insufficient
Correct Answer: B
Solution :
Pure Cu is already an excellent conductor, since it has a partially filled conduction band, further more, Cu forms a metallic crystal as opposed to the covalent crystals of silicon or germanium, so the scheme of using an impurity to donate or accept an electron does not work for copper. In fact adding impurities to copper decreases the conductivity because an impurity tends to scatter electors impeding the flow of current.
