Using the incident X-ray wavefield reconstructed by mixed states approach, a high resolution and high contrast image of the colloidal crystal structure is obtained by ptychography. The reconstructed colloidal crystal reveals domain structure with an average domain size of about 2 µm. Comparison of the domains formed by the basic close-packed structures, allows us to conclude on the absence of pure hexagonal close-packed domains and confirms the presence of random hexagonal close-packed layers with predominantly face-centered cubic structure within the analyzed part of the colloidal crystal film. The ptychography reconstruction shows that the final structure is complicated and may contain partial dislocations leading to a variation of the stacking sequence in the lateral direction. As such in this work, X-ray ptychography is extended to high resolution imaging of crystalline samples.</dcterms:abstract> <dc:contributor>Gorobtsov, Oleg Yu</dc:contributor> <dc:creator>Dzhigaev, Dmitry</dc:creator> <dc:creator>Lazarev, Sergey</dc:creator> <dc:contributor>Lazarev, Sergey</dc:contributor> <dc:contributor>Rose, Max</dc:contributor> <dc:creator>Gorobtsov, Oleg Yu</dc:creator> <dc:contributor>Kurta, Ruslan P</dc:contributor> <dc:creator>Zozulya, Alexey V</dc:creator> <dc:creator>Vartanyants, Ivan A</dc:creator> <dc:creator>Kurta, Ruslan P</dc:creator> <dc:creator>Besedin, Ilya</dc:creator> <dcterms:issued>2018</dcterms:issued> <dc:contributor>Dzhigaev, Dmitry</dc:contributor> <dc:creator>Shabalin, Anatoly G</dc:creator> <dc:contributor>Vartanyants, Ivan A</dc:contributor> <dc:creator>Rose, Max</dc:creator> <dc:language>eng</dc:language> <dspace:isPartOfCollection rdf:resource=""/> <dc:contributor>Besedin, Ilya</dc:contributor> </rdf:Description> </rdf:RDF>
