Find the conductivity of silicon (a) in intrinsic condition at a room temperature of 300 °K, (b) with donor impurity of 1 in 108, (c) with acceptor impurity of 1 in 5 x 107 and (d) with both the above impurities present simultaneously. Given that n for silicon at 300 °K is 1.5 x 10¹0 -3 cm³, H₁ = 1300 cm²/V-s, μ = 500 cm²/V-s, number of Si atoms per cm³ = 5 123 x 10²².
