Insulator-Metal Transition and Conduction Processes in Trans-Polyacetylene
Published online by Cambridge University Press: 25 February 2011
Abstract
We show by calculations for a chain of stage-1 (16.7%) potassium-doped (CH)x that the metallic state is obtained by adding to the Su-Schrieffer-Heeger Hamiltonian the Coulomb potential of the doping ions and solitons on other chains. Good agreement with the measured Pauli susceptibility is obtained. Adding interchain coupling is found to lead to essentially the same density of states.
