The conductivity of an intrinsic semiconductor depends of tempareture as`(sigma)=(sigma_0)e^(-Delta E//2kT),`where `(sigma_0)`is a constant.find the temperature at which the conductivity of an imtrinsic germanium semoconductor will be double of its value at T=300 K .Assume that the gap for germanium is 0.650 eV and remains constant as the temperature os increased.
