Germanium is doped with 5 x 1015 donor atoms per cm³ at T = 300 K. The dimen- sions of the Hall device are d = 5 x 10³ cm, W = 2 x 102 cm, and L = 10-¹ 10¹ cm. The current is I, = 250 μA, the applied voltage is V, = 100 mV, and the magnetic flux density is B₂ = 500 gauss = 5 x 10-2 tesla. Calculate: (a) the Hall voltage, (b) the Hall field, and (c) the carrier mobility.
