The Meyer-Neldel rule for dc activation processes in mixed isoelectronic chalcogens systems

►MNR for dc transports in Se-like (1D) structure systems. ►1Comparison between lone-pair and tetrahedrally bonded materials. ►EMN > 0 in amorphous phases whereas EMN < 0 for crystalline ones. ►Current models correlated true prefactor (σ00) and MN energy (EMN). ► Multiple excitations entropy term included in the apparent prefactor (σ0).
