摘要： This paper describes the accepted meaning of the term`negative resistance' and its use in the literature, and discusses the features in the previously published data on QTCTM (market name of a metal--polymer composite) that show that the non-linear, hysteretic current voltage characteristics are not caused by Joule heating. The benefit of the high metal filler loading in QTCTM and other unique features of this composite are reviewed.
