If the density of states is N(E)and the occupancy probability is P(E), then the density of unoccupied states is:
A)N(E)+ P(E)
B)N(E)/P(E)
C)N(E)- P(E)
D)N(E)P(E)
E)N(E)(1 − P(E))

Quizplus · Accepted Answer

The density of unoccupied states can be calculated as the total density of states minus the density of occupied states. Therefore, the expression for the density of unoccupied states is: N(E)(1 − P(E)). Thus, option E is the correct choice.
