SOLVED:In an intrinsic semiconductor, the band gap is so small that the Fermi-Dirac distribution results in some electrons populating the conduction band. It follows from the exponential form of the Fermi-Dirac distribution that the conductance G, the inverse of the resistance (with units of siemens, .1 S=1 Ω^-1), of an intrinsic semiconductor should have an Arrhenius-like temperature dependence, shown in practice to have the form G=G0 e^-E8 / 2 k T where Es is the band gap. The conductance of a
