Description
This session is dedicated to the outstanding contributions of Sunil Sinha in the field of Surface Scattering.
The capillary wave model of a liquid surface predicts both the X ray specular reflection and the diffuse scattering around it. A quantitative method is presented to obtain the X-ray reflectivity (XRR) from a liquid surface through the diffuse scattering data around the specular reflection. With this approach the entire Qz-dependent reflectivity profile can be obtained at a single, fixed...
Poly(3-hexylthiophene) (P3HT) is a regioregular conducting polymer widely used in the manufacture of field-effect transistors and photovoltaic cells [1,2]. Device performance strongly depends on the organization of the polymer, which is significantly influenced by the deposition method. Classical deposition techniques as drop casting or spin-coating lead to heterogeneous materials. We formed...
In nuclear fusion reactors, the divertor is the most stressed part of the physical barrier facing the plasma. The divertor extracts the heat and particles as helium (He), deuterium and tritium from the plasma. In recent reactors like WEST, ASDEX-upgrade, EAST or ITER, tungsten (W) has been chosen as material of the divertor. In the case of ITER, the most powerful fusion reactor currently under...
We now take it for granted that scattering a powerful enough X-ray beam from an object can in principle reveal the complete structure of the object, although we know that in practice this is not quite true, as our beams are not quite powerful enough. If the object or objects are deposited on a smooth reflecting featureless substrate, or if they are part of the fluctuations of the substrate...
