Two-dimensional charge transport in self-organized, high-mobility conjugated polymers
Self-organization in many solution-processed, semiconducting conjugated polymers results in complex microstructures, in which ordered microcrystalline domains are embedded in an amorphous matrix.Expand
Electroluminescence in conjugated polymers
Research in the use of organic polymers as the active semiconductors in light-emitting diodes has advanced rapidly, and prototype devices now meet realistic specifications for applications. TheseExpand
Work Functions and Surface Functional Groups of Multiwall Carbon Nanotubes
We have studied the work function and density of states (DOS) of multiwall carbon nanotubes (MWNTs) using ultraviolet photoelectron spectroscopy (UPS). Raw MWNTs were purified by successiveExpand
Light-emitting diodes based on conjugated polymers
CONJUGATED polymers are organic semiconductors, the semiconducting behaviour being associated with the π molecular orbitals delocalized along the polymer chain. Their main advantage overExpand
High-resolution inkjet printing of all-polymer transistor circuits.
It is shown that the use of substrate surface energy patterning to direct the flow of water-based conducting polymer inkjet droplets enables high-resolution definition of practical channel lengths of 5 micrometers, and high mobilities were achieved. Expand
Role of intermolecular coupling in the photophysics of disordered organic semiconductors: aggregate emission in regioregular polythiophene.
We address the role of excitonic coupling on the nature of photoexcitations in the conjugated polymer regioregular poly(3-hexylthiophene). By means of temperature-dependent absorption andExpand
General observation of n-type field-effect behaviour in organic semiconductors
It is demonstrated that the use of an appropriate hydroxyl-free gate dielectric—such as a divinyltetramethylsiloxane-bis(benzocyclobutene) derivative (BCB; ref. 6)—can yield n-channel FET conduction in most conjugated polymers, revealing that electrons are considerably more mobile in these materials than previously thought.

Light-emitting diodes based on conjugated polymers
Nature 347, 539-541 (1990) IN the published version of this paper the name of one of the authors was incorrectly cited as P. L. Burns rather than P. L. Burn. His address is the University ChemicalExpand
Effect of interchain interactions on the absorption and emission of poly(3-hexylthiophene)
The absorption spectrum of polythiophene and its derivative poly(3-hexylthiophene) (P3HT) is usually described in terms of an intrachain exciton coupled to a single phonon mode. We show that thisExpand
