Journal ArticleDOI
Charge transport in LB microsandwiches
TL;DR: In this paper, it was shown that it is possible to prepare short-circuit free LB sandwiches of a few monolayers only, if the cross sectional area is in the order of 10μm × 100μm.
Journal ArticleDOI
SWNT probed by multi‐frequency EPR and nonresonant microwave absorption
Björn Corzilius,Klaus-Peter Dinse,Kenji Hata,Miroslav Haluska,Miroslav Haluska,Viera Skakalova,S. Roth +6 more
TL;DR: In this paper, the authors applied multi-frequency EPR i ip to 319 GHz and found a much lower concentration of metallic tubes in arc material, which might be also caused by the high amount of residing catalyst.
Journal ArticleDOI
Conductivity and magnetoresistance of polyacetylene fiber network
TL;DR: In this article, the four-probe conductivity and magnetoresistance in micron-scale polyacetylene (PA) fiber networks were measured and a remarkably weaker temperature dependence of resistivity compared to that of the bulk PA film was observed.
Book ChapterDOI
Influence of the Conjugation Length of Polyacetylene Chains on the DC-Conductivity
TL;DR: In this article, the influence of doping species and concentration on the transport properties of conjugated double-bonded polymers has been studied, and the effect of defects on the conjugation of double bonds in polyacetylene has been investigated.
Journal ArticleDOI
Characterization of Carbon Nanotubes by optical spectra
M. Kaempgen,U. Dettlaff,S. Roth +2 more
TL;DR: In this paper, the optical spectra of carbon nanotubes in the infrared region is used to calculate the diameter distribution and to estimate the ratio between metallic and semi conducting tubes as well.
