Anisotropic Optical Properties of Pure and Doped Polyacetylene.
Abstract
Optical absorption and reflection measurements have been carried out on pure and doped polyacetylene films. The absorption data are consistent with a model of (CH)x as a direct gap quasi-ld semiconductor; doping with AsF5 or iodine introduces absorption within the gap, but appears to leave the interband transition intact. The anisotropic reflectance from partially aligned films and the increased optical anisotropy upon doping provide evidence of quasi-ld behavior of the semiconducting pure polymer and the metallic doped polymer.
