(author), TNO Industrie en Techniek (author)We report on the sensitization of a p-type inorganic semiconductor, NiO, by n-type conjugated polymers. NiO thin films were deposited using RF sputtering in pure Ar (NiO A) or in Ar + O<sub>2</sub> (90% + 10%) (NiO B). XPS and Kelvin probe measurements indicate the incorporation of oxygen in NiO B leading to the formation of electron-accepting...article 2010

(author), TNO Industrie en Techniek (author)Thin polymer substrates are promising materials for flexible electronics with many advantages. However, the dimensional stability of polymer substrates is low. Nowadays, this is overcome by laminating polymer substrates onto a rigid carrier. Nevertheless, carrier-less processing will be a foreseen next step for future manufacturing of plastic...article 2010

Zhang, Y. (author), de Boer, B. (author), Blom, P.W.M. (author), TNO Industrie en Techniek (author)We demonstrate that the electron transport in conjugated polymers as poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) is limited by deep traps that mask the intrinsic transport properties of free electrons in these materials. These traps can be deactivated by addition of the n -type dopant decamethylcobaltocene (DMC). By...article 2010
