Electrical Conductivity of Halogen-Doped Polyacetylene.
Abstract
When films of semiconducting polymer, trans-polyacetylene, (CH)(x), are exposed to chlorine, bromine or iodine vapor, uptake of halogen occurs; and the conductivity increases markedly, over seven orders of magnitude in the case of iodine. Although the randomness of the halogenated polyacetylene may be playing an important role, the behavior is like that of a series of semiconductors with activation energies which vary with halogen content. Transport and infrared studies of the most highly conducting composition are suggestive of metallic behavior. (Author)
