If an Electric Field Is Applied to a Metal

question 8

Multiple Choice

If an electric field is applied to a metal:

• A)very few electrons are excited into the conduction band.
• B)electrons having energies near the Fermi energy require only a small amount of additional energy from the applied field to reach nearby empty energy states.
• C)electrons having energies near the bottom of the band require only a small amount of additional energy from the applied field to reach nearby empty energy states.
• D)the principal mode of conduction is through the motion of holes in the filled part of the band.
• E)the Fermi energy Ef becomes equal to the applied electric field E.
