Determine the number density of donor atoms which have to be added to an intrinsic germanium semiconductor to produce an \( n \)-type semiconductor of conductivity \( 5 \Omega^{-1} \mathrm{~cm}^{-1} \), given that the mobility of electron in \( n \)-type germanium is \( 3900 \mathrm{~cm}^{2} \mathrm{~V}^{-1} \mathrm{~s}^{-1} \). Neglect the contribution of holes to conductivity. [Ans. \( 8 \cdot 012 \times 10^{15} \mathrm{~cm}^{-3} \) ]
