Witryna11 kwi 2024 · Calculation: Since the intrinsic carrier concentration of Germanium is of the order of 10 13, and the given donor density is of the order of 10 20, we can write: n 0 = N d = 10 17 atoms/cm 3. μ n = 700 cm 2 /V-sec. Since there is no acceptor impurity, p 0 << n 0 and can be easily neglected and the resistivity becomes: ρ ρ = 1 q n 0 μ n.
