We have investigated the effects of temperature variation on colloidal solutions of the electrode polymer poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) and its consequences for photovoltaic devices using conjugated polymer b

We investigate the mechanism of operation of low-power write-once-read-many-times (WORM) memory devices based on injection of electrons from ZnO into PEDOT:PSS (polydioxythiophene doped with polystyrenesulfonic acid). Using Raman spectroscopy and in

In conjugated polymers, the process of interconversion between singlet and triplet bound charge-pairs is important in determining the efficiency limits both for light-emitting diodes (LEDs) and for photovoltaics. We probe the kinetics of spin-mixing

This paper studies the self-assembly on gold surfaces of 1,4-ethynylphenyl-4′-ethynylphenyl-2′-nitro-1-benzene-dithiolate (EP2NO2), a substituted phenylene ethynylene trimer with applications in molecular electronics. We develop an ellipsometric

We have studied infrared absorptions in working polymer light-emitting diodes due to the presence of polarons and triplet excitons. The polaron population is found to be proportional to the applied voltage, providing direct evidence for space-charge-

We report the use of environmental scanning electron microscopy (ESEM) to determine the phase separation in the cross-section of a 200 nm thick polyfluorene blend film, of the type used in polymer photovoltaic devices and LEDs. The micron and sub-mic
