Exact and asymptotic expressions for the specific conductivity and the temperature coefficient of resistance (TCR) of two-layer metal polycrystalline films have been derived. A verification of the relations for the TCR has been performed using experimental data for (Cr, Cu, Sc)- and (Ni, Co, Cr)-based two-layer films. The theoretical and experimental results for the TCR. are qualitatively consistent.
