摘要：

Conjugated polymers, which, when doped, display metallic levels of conductivity, are materials in which there is considerable interest, with possible applications in optoelectronics, rechargeable batteries and electrical screening. These polymers have been studied by two scanning probe techniques. Molecular images of undoped poly(p-phenylene vinylene) (PPV) and poly(3-hexylthienylene) (P3HT), deposited on gold, silver and graphite substrates, have been obtained by scanning tunnelling microscopy, with local alignment of chains observed on the surface. Results from photon emission STM are also presented, and these provide some spectroscopic information about the band gaps and gap states of the polymers, and about plasmon states of the metal substrates.
