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