Solitary-waves and low temperature conductivity in the 1-D compounds K2Pt(CN)4X0.3-3.2H2O (X = Br, Cl)

Abstract

We report careful conductivity measurements on KCP(Br) and KCP(Cl) in the low temperature region. We find that below 50 K, the activation energy lowers to a value which is inconsistent with the Peierls gap. According to Rice et al.'s theory and by correlation with recent NMR data, we suggest that this behaviour is due to current carrying solitary waves. A decomposition of the conductivity shows that solitons should be the main transport mechanism below 40 K in both the compounds. © 1982.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
