  1. Question 1

    Q1. The Fermi energy is the energy of?

    • A) The highest occupied state at T = 0 K
    • B) The lowest unoccupied state at T = 0 K
    • C) The average energy of electrons
    • D) The energy of the conduction band edge

    Answer: The highest occupied state at T = 0 K

    Explanation: At T = 0 K, all states below EF are filled, making EF the energy of the highest occupied state.
