Composition dependent electronic conductivities and hall coefficients of mixed ionic‐electronic conductors. Part III: Beta silver sulfide revisited

Abstract

In a previous paper (I) we presented the composition dependent electronic conductivity and Hall coefficient of β‐Ag2+δS at different temperatures. The mobility of conduction‐band electrons was found to vary with temperature as T−3/2. In this paper we point out that, due to a temperature dependent effective electron mass, the relaxation time of conduction‐band electrons varies as T−1 and not as T−3/2.
