| Abstract: | The combination of grazing-incidence small-angle x-ray scattering (GISAXS)with tomographic methods and phase retrieval is proposed for thereconstruction of the three-dimensional (3D) electron density of nanometersized objects. In this approach GISAXS data from a small object arecollected successively at different azimuthal angular positions. This 3Dintensity distribution in reciprocal space is used for the phase retrievaland reconstruction of the 3D electron density. The power of our approach isdemonstrated in a series of calculations performed in the frame ofkinematical and distorted-wave Born approximation (DWBA) theories for thecase of GISAXS scattering on a 200?nm island in the form of truncatedpyramid. |
