Expert Solution & Answer
Answer to Problem 40A
As conductivity is directly proportional to the temperature, therefore, as the temperature increases on heating, conductivity also increases.
Explanation of Solution
Introduction: The conductivity of a semiconductor increases on heating.
Conductivity of a semiconductor depends upon two factors, the concentration of free carriers available to conduct current and their mobility. Both mobility and carrier concentration are temperature dependent. Thus, the conductivity can be expressed as a function of temperature, 
where 
is the conductivity and T is the temperature.
Conclusion: As conductivity is directly proportional to the temperature, therefore, as the temperature increases on heating, conductivity also increases.
