A non-degenerate n-type semiconductor has 5% neutral dopant atoms.
Its Fermi level is located at 0.25 eV below the conduction band (EC) and the donor energy level (ED) has a degeneracy of 2.
Assuming the thermal voltage to be 20 mV, the difference between EC and ED (in eV, rounded off to two decimal places) is
