Metal-insulator transition in PF6 doped polypyrrole: interchain charge transfer versus electronic correlation
H. C. F. Martens, H. B. Brom, R. Menon
We performed dielectric spectroscopy on polypyrrole near the metal-insulator transition (MIT) down to 2 K. We evaluate the dependence of the plasma frequency and the scattering tim…
The metallic state in disordered quasi-one-dimensional conductors
H. C. F. Martens, J. A. Reedijk, H. B. Brom +2
The unusual metallic state in conjugated polymers and single-walled carbon nanotubes is studied by dielectric spectroscopy (8--600 GHz). We have found an intriguing correlation bet…
Localized and Delocalized Charge Transport in Single-Wall Carbon-Nanotube Mats
O. Hilt, H. B. Brom, M. Ahlskog
We measured the complex dielectric constant in mats of single-wall carbon-nanotubes between 2.7 K and 300 K up to 0.5 THz. The data are well understood in a Drude approach with a n…
Dopant-induced crossover from 1D to 3D charge transport in conjugated polymers
J. A. Reedijk, H. C. F. Martens, H. B. Brom +1
The interplay between inter- and intra-chain charge transport in bulk polythiophene in the hopping regime has been clarified by studying the conductivity as a function of frequency…
