In the past few years, organic film prepared on the silicon (Si) surface has become attractive owing to the wide range of potential application, low cost and good performance. In this paper, perfluorinated organic film was prepared on the Si surface in aqueous solution using one-step dipping method. On the Si surface, 4-nitrobenzene diazonium (NBD) tetrafluoroborate was firstly reduced with the presence...
Summary form only given. Plasma polymerization offers an ecological, potentially tunable route to selectively and controllably change the physics and chemistry of the outer surface of a material. It presents an exciting chance to produce pinhole free, conformal thin films, containing high concentrations of specific functional groups at the surface, deposited on most supports, by complex reactions...
We report studies of charge recombination and photovoltaic device performance in structures consisting of a fluorene-bithiophene co-polymer and nanocrystalline TiO/sub 2/. Efficient photoinduced charge transfer is observed using a TiO/sub 2/ film of high interfacial area while charge recombination is remarkably slow (/spl sim/ms). The influences of thickness, surface morphology, top contact material,...
