Determine the number density of donor atoms which have to be added to an intrinsic germanium to produce an `n`-type semiconductor of conductity `0.06S
Determine the number density of donor atoms which have to be added to an intrinsic germanium to produce an `n`-type semiconductor of conductity `0.06Sm^(-1)`. Given the mobility of electrons `=0.39m^(2)V^(-1)s^(-1)`. Neglect the contribution of holes to the conductivity.
