Electrical conductivity of (SN) x

Abstract

Measurements of the b-axis conductivity of polymeric sulfur nitride (SN) x from 4.2–300K are reported for samples having different polymerization times. A general increase in the conductivity was found with longer polymerization times leading to room temperature conductivities 1200–3700 (Ω-cm) −1 and resistance ratios 50–205. The temperature dependence of the resistivity can be represented by Matthiessen's rule showing the intrinsic resistivity over a broad temperature range 15< T<250K follows a T 2 form which is discussed in terms of electron-electron scattering.
