C. K. Chiang,C. R. Fincher,Yung Woo Park,Alan J. Heeger,H. Shirakawa,E. J. Louis,S. C. Gau,Alan G. MacDiarmid +7 more
TL;DR: In this paper, a metal-to-insulator transition at dopant concentrations near 1% was shown for polyacetylene, a new class of conducting polymers in which the electrical conductivity can be systematically and continuously varied over a range of eleven orders of magnitude.
Journal ArticleDOI
Structural Determination of the Symmetry-Breaking Parameter in trans-(CH) x
TL;DR: The magnitude of the symmetry-breaking dimerization distortion has been determined by analysis of x-ray scattering data from trans-${(mathrm{CH})}_{x}$ ${u}_{0}\ensuremath{\simeq}0.03$ \AA{}.
Journal ArticleDOI
Donor and acceptor states in lightly doped polyacetylene, (CH) x
Journal ArticleDOI
Polyacetylene, (CH)x: n‐type and p‐type doping and compensation
TL;DR: In this article, a series of experiments are reported which demonstrate that donors or acceptors can dope polyacetylene to n type or p type, respectively, and that the two kinds of dopants can compensate one another.
Journal ArticleDOI
Electronic structure of polyacetylene: Optical and infrared studies of undoped semiconducting (CH) x and heavily doped metallic (CH) x

TL;DR: In this article, a Kramers-Kronig analysis of the reflection data has been carried out to obtain an intrinsic dc conductivity for metallic polyacetylene polysilicon.
