The conductivity of an intrinsic semiconductor depends on temperature as , where is a constant. Find the temperature at which the conductivity of an intrinsic germanium semiconductor will be double of its value at . Assume that the gap for germanium is and remains constant as the temperature is increased.
View answer and explanation
Correct option: A
Option A () is correct because it is the temperature at which the conductivity of the germanium semiconductor doubles, calculated using the given formula.
