The number desnity of donor atoms which have to be added to an intrinsic germanium semiconductor  to produce an n-type semiconductor of conductivity `5 ohm^(-1) cm^(-1)` is `axx10^(15)cm^(-3)`. Given that the mobility of electron in n-type Ge is `3900 cm^(2)//Vs`, Neglect the contribution of holes to conductivity. What is the integer value of a?
