LETTER TO THE EDITOR

In my article (N. N. Sirota, “On the temperature dependence of the electrical conductivity of solids”), published in DAN, vol. 143, No. 3, 1962, in the original formula (2), unfortunately, the coefficients (a_T) and (a_C) were omitted before the mean-square displacements (\overline{u^2_{S,T}}) and (\overline{u^2_{S,C}}). These coefficients are connected with the cross sections for scattering of electrons by phonons and impurities and with the densities of dynamic and static inhomogeneities. Their proper allowance changes some of the temperature dependences given in the text for the case of their constancy, and changes the explanation of the temperature minimum of the resistance of Ag and Au. In particular, the quantity (a_T) is proportional to the energy of the thermal motion of the lattice referred to the temperature,

[
a_T \sim \frac{c}{3RT}\int_0^T c_v\,dT.
]

Formulas (5), (6), (7) must contain the factor (a'_T = a_T + c_1). Formula (8) must have the form:

[
\rho = \rho_{c_0} + \frac{m^}{n_0 e^2}
\left[
a_T \overline{u^2_{S,T}} + a_C \overline{u^2_{S,C}}
\right]
\frac{B}{1+\dfrac{n_{01}m^}{n_1 m^*_1}e^{-\Delta E/2kT}}
=
]

[
= \rho_{c_0} + \frac{m^}{n_0 e^2}
\left{
\left[
\frac{\hbar^2\cdot 3}{kM\theta}
\left(
\frac{\Phi(\chi)}{\chi}+\frac{1}{4}
\right)
\right]a_T
+ a_C \overline{u^2_{S,C}}
\right}
\frac{B}{1+\dfrac{n_{01}m^}{n_0 m^*_1}e^{-\Delta E/2kT}}.
