متن کاملMeasurement of Transient Photo-induced Changes in Thin Films at J-PARC – Time-resolved Neutron Reflectivity Measurements of Silver Photo-diffusion into Ge-chalcogenide Films
Study on photo-induced changes for specific light-sensitive materials is fascinating from both academic and application points of view because it is one of the frontiers in materials science including concepts of electron-excitation and non-equilibrium state, and the materials can be controlled spatially by illuminated area from distant place [1]. With the aid of significant development of ligh...
متن کاملPhoto-induced halide redistribution in organic–inorganic perovskite films
Organic-inorganic perovskites such as CH3NH3PbI3 are promising materials for a variety of optoelectronic applications, with certified power conversion efficiencies in solar cells already exceeding 21%. Nevertheless, state-of-the-art films still contain performance-limiting non-radiative recombination sites and exhibit a range of complex dynamic phenomena under illumination that remain poorly un...
متن کاملFriction model of Photo-induced Reorientation of Optical Axis in Photo-oriented Langmuir-Blodgett Films
A model of the Photo-induced Optical Anisotropy (POA) is proposed for molecular films consisting of ordered domains. The model describes the molecular motion in an anisotropic molecular field at different rates of collisions (friction) between, respectively, excited and ground state molecules and a substrate under polarized light illumination into a molecular absorption band. It is shown that i...
متن کاملThickness induced structural changes in polystyrene films.
Changes to the structure of polystyrene melt films as measured through the spectrum of density fluctuations have been observed as a function of film thickness down to the polymer radius of gyration (Rg). Films thicker than 4Rg show bulklike density fluctuations. Thinner films exhibit a peak in S(q) near q=0 which grows with decreasing thickness. This peak is attributed to a decreased interpenet...
