Temperature coefficient of resistivity of silicon and
Temperature coefficients for the resistivity of n- and p-type germanium and silicon in the neighborhood of room temperature have been determined over a wide range of resistivity. Linear temperature coefficients have been found for the extrinsic exhaustion region (<5 Ω-cm for germanium and <500 Ω-cm for silicon). The results are presented as plots of temperature coefficient against resistivity at 23°C.
