The conductivity has a strong dependence on temperature.

Work Step by Step

In a p-n junction, it is essential to recognize that the conductivity is controlled by impurity concentrations and by temperature. As a result, the model of a p-n junction predicts an exponential dependence of saturation current on the absolute temperature, as shown in equation 42.22 and discussed in the section following that equation.
