During the past decade, transport properties of conducting polymers such as doped polyacetylene and polyaniline-polyethylene oxides, were and still are intensively studied [1, 2]. These materials are significant mostly due to various possible applications in fabrication of nanodevices. Polymer-based devices should have advantages of low cost and flexible, controlled chemistry. Also, there are s...

The electrodynamic response of DNA in the millimeter wave range is investigated. By performing measurements under a wide range of humidity conditions and comparing the response of single-stranded DNA and double-stranded DNA, we show that the appreciable ac conductivity of DNA is not due to photon-assisted hopping between localized states but is instead due to dissipation from dipole motion in t...

The temperature dependence of electrical conductivity and conductivity anisotropy of FeCI3 doped stretch-oriented polyacetylene film at different doping levels were measured by using Montgomery technique. The increase of conductivity anisotropy upon doping is related to the aligned fibrillar structure and the interfibrillar contact effect. Weak temperature dependence, the slight decrease at low...

N TiO2 thin films have attracted considerable attention due to their pivotal role in energy conversion and environmental applications, including photovoltaics, 3 photocatalysis and remediation of hazardous waste, 5 electrochromic windows and displays, and chemical sensors. However, the underlying mechanisms responsible for electron transport through nanoporous TiO2 remain only partially underst...
