Which of the following is true for a p-type semiconductor?

Step-by-step solution

In a p-type semiconductor, trivalent impurity atoms (such as boron, aluminum, or gallium) are added to an intrinsic semiconductor. These impurity atoms create an acceptor energy level which lies just above the valence band. Electrons from the valence band can easily transition to this acceptor level at room temperature, leaving behind holes in the valence band. Thus, holes become the majority charge carriers. Therefore, the impurity level lies just above the valence band. Answer: The impurity level lies just above
