The electrical properties such as the electronic and ionic conductivities, Hall coefficients, etc. of the alloys Ag 2 (Te, Se; Te, S; Se, S) are studied with use of the galvanic cell Ag|AgI|specimen|Pt, the excess Ag content being controlled by sending a current across the cell. The electrical properties of these alloy systems change continuously in the α phase as the missing ration x in varied, while they change discontinuously or rapidly at certain x 's in the β phase. The experimental results are compared with theory under simplifying assumptions such as the energy-independent relaxation time and the energy-momentum relation given by \(\varepsilon{=}\hbar^{2}\textbf{\itshape k}^{2}(1-B\textbf{\itshape k}^{2})/2m^{*}\).
