Abstract

Results of electrical conductivity and thermopower measurement on [CH(FeCl4)_y]_x are presented, where y covers the full doping range. The semiconductor-metal transition is evident and leads to a qualitative change in temperature dependence of the conductivity and thermopower. The analysis of the metallic thermopower data indicates the Kondo-like effect originated from the coupling between the (CH)_X chain and the dopant located near the chain. As a consistent interpretation of our data, we propose a mechanism of the semiconductor-metal transition in doped (CH)_X; the one dimensional intersoliton electron tunneling model.
