Abstract:

A study of the electrical conductivity of the halogen doped trans-polyacetylene system CHx, is reported. When films of trans-CHx are exposed to chlorine, bromine or iodine vapor, uptake of halogen occurs and the conductivity increases markedly, over eight orders of magnitude in the case of iodine. The behavior of the halogenated polyacetylene is like that of a series of semiconductors with activation energies which vary with halogen content. The heavily doped polyacetylene shows metallic behavior with the semiconductor-metal transition near 2-3 dopant concentration. The results are discussed in terms of a model of the doping process based on charge transfer. Author
