摘要: The physics of quasi-one-dimensional solids which undergo a Peierls distortion, such as the organic material TTF-TCNQ (tetrathiofulvalinium-tetracyanoquinodimethan) is discussed. In particular, effect fluctuations into Fr\"ohlich superconducting state on free energy and electrical conductivity examined theoretically at temperatures above that distortion. A phenomenological approach used, but physical basis for microscopic treatment given results are compared with BCS state. It found give paraconductivity too small to account extraordinary peaks reported TTF-TCNQ.
