Given that the width of an energy band is 10 eV, calculate the following, in cm and eV- unit. Consider temperature as 420 K. I) The density of states at 8 kT above the bottom of the band. II) The number of states per unit volume within an energy -3 range of 8 kT to 46 kT from the bottom of the band. Note that this is NOT a small energy range.
