Question: Find the probability that energy state in copper 0.10 eV above the Fermi energy (EF = 7.03 eV) is occupied at T = 300K.

b) Calculate the Fermi speed of a electron for copper. The Fermi energy for copper at T=0K is 7.03 eV.

c) The donor energy levels in an n-type semiconductor are 0.012 eV below the conduction band. Find the temperature (T) for which kBT = 0.012 eV. (kB = 1.38x10-23 J/K).

d) When a thin slab of semiconductor material is illuminated with monochromatic electromagnetic radiation, most of the radiation is transmitted through the slab if the wavelength is greater than 1.85 mm. For wavelengths less than 1.85 mm, most of the incident radiation is absorbed by the slab. Determine the energy gap of the semiconductor slab.
