For intrinsic semiconductors, the concentration of intrinsic carriers ni depends on the temperature of theas follows:Thus, a graph of (ln ni) as a function of 1 / T (K) –1 must be linear and have a slope of (-Ee / 2k).

2. For a semiconductor with a constant mobility ratio b=μn/μp > 1 independent of impurity concentration, find the maximum resistivity ρm in terms of the intrinsic resistivity ρi and the mobility ratio.(HINT: First, express the conductivity as the sum of the contributions of the electrons and holes. The expression will contain both n and p. Eliminate one of them by using the fact that their product is a constant at a given temperature. Next, to obtain the maximum resistivity, take a derivative with respect to the carrier concentration (which you did not eliminate in the previous step). Then obtain the ratio of ρm /ρi. This ratio should be independent of the carrier concentrations.)
