Abstract
In this thesis I have calculated the electrical conductivity and drift mobility in heavily doped n-type
silicon in the presence of band tail effects considering mixed scattering of ionized impurities and
acoustic phonons.
The results of the calculation show that the electrical conductivity can be as much as 58% lower
than the value obtained by using parabolic density of states and the drift mobility in heavily doped
n-type silicon on the other hand is 40% lower than the value calculated using parabolic density of
states
