Abstract
The optical properties of electrochemically-doped [CH(ClO4)y]x are discussed. The heavily-doped regime, best described as a gapless incommensurate Peierls insulator, is characterized by high dc conductivity, a large Pauli susceptibility and by the disappearance of the original interband transition of undoped (CH)x. The optical spectrum shows a pseudogap at -0.5 eV and vibrational modes which imply that the carbon-carbon bondlength is not uniform.Keywords
