At what temperature do 1.30% of the conduction electrons in lithium (a metal) have energies greater than the Fermi energy EF, which is 4.70 eV?
If the temperature of a piece of a metal is increased, does the probability of occupancy 0.1 eV above the Fermi level increase, decrease, or remain the same?
The occupancy probability at a certain energy E1 in the valence band of a metal is 0.60 when the temperature is 300 K. Is E1 above or below the Fermi energy?
