Polymer light-emitting devices (PLEDs) with poly(2-methoxy-5-hexyloxy)-p-phenylenevinylene (OC 1 OC 6 -PPV) as the emissive layer were studied with an electron injection layer of ionomers consisting of copolymers of styrene and methylmethacrylate (PS/PMMA) with 3, 6 and 8mol% degree of sulfonation. The ionomers were able to form very thin films over the emissive layer, with less than...
The study of electrical properties of poly (ethylene terephthalate), (PET), has attracted great interest since it is used in commercial applications such as insulation in capacitors and as a charge storage device in foil electret transducers. For an accurate evaluation of its insulating and electret qualities the underlying physical mechanisms for charge transport have to be understood. Two processes...
With the widespread use of dielectric materials in high-radiation environments the behavior of the radiation-induced conductivity of dielectrics has acquired considerable importance. Numerous authors have investigated the dielectric response to short, intense bursts of radiation. The long-time behavior of the induced conductivity of insulators determines the amount of charge build-up which has been...
