Using Equation 12.36 and the results of Problem 12.33, determine the temperature at which the electrical conductivity of intrinsic germanium is 22.8 (Ω • m)–1.

Problem 12.33

At temperatures near room temperature, the temperature dependence of the conductivity for intrinsic germanium is found to be given by

where C is a temperature-independent constant and T is in Kelvins. Using Equation 12.36, calculate the intrinsic electrical conductivity of germanium at 150°C.
