Morphology and Charge Transport in Conjugated Polymers
Determining the relationship between charge transport and morphology is key to increasing the charge carrier mobility of conjugated polymers. This review details a fundamental study of the charge transport and morphology of regioregular poly(3-hexylthiophene) and sets out general principles for obtaining high charge carrier mobilities. The basis for this study was the finding that despite being...
متن کاملCharge transport and structure in semimetallic polymers
Owing to changes in their chemistry and structure, polymers can be fabricated to demonstrate vastly different electrical conductivities over many orders of magnitude. At the high end of conductivity is the class of conducting polymers, which are ideal candidates for many applications in low-cost electronics. Here, we report the influence of the nature of the doping anion at high doping levels w...
متن کاملVertical charge transport in conjugated polymers
Conjugated polymers are novel organic electronic materials highly important for organic photovoltaic applications. Charge transport is one of the key properties which defines the performance of conjugated polymers in electronic devices. This work aims to explore the charge transport anisotropy in thin films of P3HT, one of the most common conjugated polymers. Using X-ray diffraction techniques ...
متن کاملCharge Transport in Conducting Polymers: Polyacetylene Nanofibres
The preparation of individual polyacetylene nanofibres has allowed a more probing investigation of the properties of polyacetylene. A significant discovery is that at low temperatures, polyacetylene nanofibres show temperature-independent Zener-type tunnelling, that we suggest is tunnelling of the conjugated-bond pattern along single polyacetylene chains. At higher temperatures, the current sho...
متن کاملCharge transport in DNA.
The base pair stack within double helical DNA provides an effective medium for charge transport. The DNA pi-stack mediates oxidative DNA damage over long molecular distances in a reaction that is exquisitely sensitive to the sequence-dependent conformation and dynamics of DNA. A mixture of tunneling and hopping mechanisms have been proposed to account for this long-range chemistry, which is gat...
