Low-temperature specific heat of polysulfur nitride, (SN)x
Abstract
Measurements of the specific heat of crystalline (SN)x in the region 1.5-10°K are reported. A linear temperature contribution to the specific heat is found and interpreted as arising from an electron state density of 0.18 state/(eV spin molecule) and a one-dimensional tight-binding conduction band of width 0.9 eV. Analysis of the lattice specific-heat contribution supports existing evidence that (SN)x is a highly anisotropic crystalline polymer and suggests a possible explanation for the apparent absence of a Peierls transition. © 1975 The American Physical Society.
