Abstract: Resonant electron scattering in $p$-Ag$_2$Te at acceptor concentrations $N_{\mathrm{a}}$ $\le$ 4.2 $\times$ 10$^{16}$ cm$^{-3}$ has been observed in the temperature range of 50–80 K. The contribution of the resonant scattering to the temperature dependences of the conductivity $\sigma(T)$ and thermopower $\alpha_0(T)$ has been calculated. It is shown that this contribution exceeds that of charge carrier scattering by acoustic phonons.
